New CDMA iPhone Creates Doubt on Jailbreak Possibilities
The CDMA iPhone will be released on February 10, a month from now, and until one of those hackers actually handles it, we’ll have no way of knowing whether current jailbreak tools will work or not. But chances are a CDMA iPhone jailbreak tool will indeed be offered sooner or later.
Step-by-Step Procedure to Jailbreak iPhone on unlockediPhone.info
The company www.unlockediPhone.info has clearly given more importance to user-friendliness since the actual unlocking takes lesser time to complete than one might imagine. Unlocking the iPhone is now a step-by-step process of firstly selecting the right version of unlocking software custom built for the particular model of iPhone one owns and having once paid and installed the same, the customer is no longer restricted to use their iPhone on only one network. There are video tutorials to help the user along the way in case of any doubts and this move is appreciated by the software’s users many of whom do not have much experience using a computer let alone in unlocking an iPhone without issues. Had I known earlier that unlocking my iPhone was this easy and safe, I wouldn’t have waited so long to do it. was the feedback given by one customer in Maryland.
How Jailbreaking Differs from Sim Unlocking
Jailbreaking is different from SIM unlocking, which, once completed, means that the mobile phone will accept any SIM card without restriction. Cydia creator Jay Freeman estimates that more than 10% of all iPhones are jailbroken.
Carrier locks, otherwise known as SIM locks or network locks, are a feature of GSM phones, not CDMA phones. GSM phone service subscribers have SIM (subscriber identity modules) cards which, when inserted in their GSM phones, identify each subscriber on the network. Subscribers can change devices simply by popping out their SIM card and inserting it into another device. GSM phone manufacturers provide hardware and software features that allow network providers to “lock” phones to accept only certain SIM cards. For example, only SIM cards that contain particular mobile country codes (MCCs) or mobile network codes (MNCs) – such as AT&T.

Top 5 CDMA phones in India
Dec 4th
It is quite interesting that hundreds and thousands of articles are written on Mobile phones, but majority of them only talk about GSM phones. CDMA has not really been written much about. I have been using a Reliance CDMA connection for almost 4-5 years now and I find CDMA service more cost effective than its GSM counterparts. So I decided to give CDMA phones a little limelight as well.
When I decided to write about top 5 CDMA phones, I thought it to be a very easy task. Well, it definitely was not as easy as I thought!
The CDMA Operators decided to open up for the OMH (open Market Handsets) thus rendering equality across CDMA with regards to operator selection. Like GSM, a customer has ability to choose any CDMA service provider. There have been lots of phones which support CDMA and new launches have been pretty common. Just last month LG launched 6 new CDMA OMHs. Most of the CDMA handsets have pretty much same features ranging from low-end to high-end ones. Handsets are available from 1000 Rs to 20,000 Rupees. The Handsets which really mattered were only handful of them.
Here is my Top 5 CDMA handsets which every person with CDMA must look at!

Telkom Will Exit Nigeria CDMA Mobile-Phone Business
Nov 22nd
Telkom South Africa Ltd. said it will exit the CDMA-technology mobile-phone business of its loss- making Multi-Links unit in Nigeria in the next six months.
Africa’s largest fixed-line phone company is “in the process of engaging a couple of parties with respect to the exit,” Jeffrey Hedberg, Pretoria-based Telkom’s acting chief executive officer, said on a conference call today. “Given the clear need for speed, we need to move in a way that is going to stop the burn rather than extend the burn.”
Multi-Links made a net loss of 262 million rand ($37.6 million) in the six months through September, according to a presentation today. The unit accounts for about 90 percent of Telkom’s business in Africa’s most-populous nation, Acting Chief Financial Officer Deon Fredericks said on the call. Multi-Links hasn’t made a profit since Telkom purchased it for $410 million in 2007.
The exit may cost $100 million to $180 million, excluding any money from selling physical assets such as transmission towers, Hedberg said. He said there is still “strategic potential” for the rest of the business in Nigeria, which includes 7,000 kilometers of fiber-optic cable, 2,000 kilometers of which is shared with MTN Group Ltd., Africa’s largest mobile- phone operator, and Nigeria’s Globacom Ltd.
Multi-Links has “an expansive, well-developed network, in particular its fiber-optic network which Telkom has not utilized fully to its advantage until lately,” London-based Frost & Sullivan analyst Spiwe Chireka, said in an e-mailed note today.
Data Business
Telkom is in discussions with companies in Nigeria “about increasing in-country scale and minimizing our exposure,” with the data part of the Multi-Links business that it’s keeping, Hedberg said. “We believe the bleed there is far less so we are going to take our time in order to make a good decision.”
The company’s net income fell to 1.01 billion rand in the six months through September from 39.7 billion rand a year earlier, as income of 40.4 billion rand from the sale of a stake in Vodacom Group Ltd. wasn’t repeated, Telkom said in a statement today. Total revenue dropped 6.5 percent to 18 billion rand.
Telkom shares rose 2.2 percent to 36.71 rand at 1:20 p.m. in Johannesburg trading.
Oil, gas and resources companies and banks will be targeted as customers who need fixed-line data services with the high transmission speeds that fiber can provide, Hedberg said.
Telkom must “make sure it gets things right with Multi- Link because from its current portfolio of companies, excluding South Africa, Multi-Links holds the largest potential” to make a success of Telkom’s pan-African strategy, Chireka said.
Voice Revenue
In South Africa, voice revenue has been falling as consumers substitute fixed-line for mobile services and corporate clients migrate to voice services via the Internet, said Pinky Moholi, managing director for the country. Voice revenue in the six months through September declined 19 percent to 6.9 billion rand.
In the corporate market, “rather than lose the customer totally,” Telkom aims to “at least be the seller of the data solution” and facilitate the migration to voice over the Internet, Moholi said.
Telkom launched its 8ta mobile offering in October, competing with Vodacom Group Ltd., the largest provider of mobile-phone services to South Africans, and MTN. It will spend 6 billion rand over five years rolling out its network.
“Telkom’s new mobile service is anticipated to retain and expand Telkom’s customer base while growing revenue for the company,” Chireka, said. “Competition in South African market has become cutthroat.”
Bundled Services
Customers will be able to start receiving a single bill for fixed-line voice and Internet services as well as the mobile offering by about March or April as new bundled services will be sold to new and existing customers, Moholi said.
Telkom is stabilizing its fixed-line business, said Moholi. “In order for us to up-sell broadband, we need to have fixed line into people’s homes,” she said. “If you don’t have the fixed-line you can’t even have an opportunity to up-sell those services,” she said.

Comparing CDMA And GSM Mobile Phones: Which is the Best Choice?
Sep 25th
Mobile phones today, run on one of two major telecom standards: GSM and CDMA. While choosing a carrier, you have to know whether you are going for CDMA or GSM, because each has its own unique features, advantages and drawbacks. A random decision may adversely affect your user experience.
So, let’s try to find out which among GSM and CDMA is the best choice.
CDMA or Code Division Multiple Access is the dominant network standard in the US since it was developed by Qualcomm. GSM or Global System for Mobile was developed way back in 1987 by the GSM Association and has greater international acceptance than CDMA.
CDMA Vs. GSM Phones
In terms of coverage comparison, CDMA is easily outdone by GSM. CDMA is currently supported in the US and parts of Asia while GSM is available almost all throughout the world. However, in smaller cities, towns and rural areas in the US, CDMA networks are stronger.
With a quad band mobile phone (850-1900 MHz) you can travel almost anywhere in the world and yet be connected via GSM. With CDMA that is not the case and so if you travel a lot, internationally, there is no doubt that you should get a CDMA phone.
As far as data access is concerned, CDMA scores with technologies likes EVDO making data transfer at speeds up to 2mbps a possibility. GSM used EDGE as a dedicated data transfer technology till very recently, but now HSDPA is in the horizon which should match up to EVDO.
The standard procedure followed by CDMA carriers is to program the user account information in the phone itself. So, a change of phone has to be done via the carrier, which will reprogram the same information in the new phone. GSM carriers provide removable SIM cards which can be shifted between phones, so you are more in control of how you use your number. However, a new removable User Identity Module cards are now available on some CDMA phones.
CDMA phones are generally known to consume more battery than GSM phones because their operations are more complex.
So, your choice of opting for CDMA or GSM cell phones should ultimately be decided by what you need. Simply put, unless you are a frequent flier, CDMA is as good as GSM as an option. The best Verizon Wireless phones such as the Motorola Droid X and the BlackBerry bold are CDMA devices, while AT&T offers amazing GSM phones such as the iPhone and the Samsung Captivate. So, take your pick!
Windows Phone 7 initially on GSM, then CDMA in 2011
Sep 17th
Computerworld – Windows Phone 7 devices coming this fall will initially work with GSM carriers such as AT&T and T-Mobile, but will not include carriers of CDMA technology, which include Verizon Wireless and Sprint Nextel.
“Microsoft chose to focus on delivering a great GSM version to the world first, and then a great CDMA version in the first half of 2011,” a Microsoft spokesman said Friday via e-mail.
Microsoft is “placing high-quality customer experiences above all else,” he added.
GSM is widely used throughout the world, although in the U.S., CDMA represents about half the nation’s wireless customers.
Finland-based Nokia, the largest maker of mobile phones globally, announced a push into the U.S. market earlier this week, and also said that it will not focus on further CDMA phones for the U.S., preferring GSM technology and development for 4G phones running LTE, a faster wireless standard.
The first phones running Windows Phone 7 are expected to go on sale next month, according to various reports. An Oct. 11 launch date has also been reported.
Windows Phone 7 is Microsoft’s attempt to recapture smartphone and mobile phone sales, especially to consumers, after several quarters of disappointing sales with its older brand, Windows Mobile. The OS maker is expected to take a 4.7% share of the smartphone market for 2010 and 3.9% by 2014, according to a recent Gartner forecast.
