It gets frustrated when you are unsatisfied with some service provider but you don’t have even right to switch to another service provider. This exactly happens when you are only eligible to buy iPhone on contract with some carrier which may not be your choice. For example, you are in USA and Verizon is your choice for iPhone carrier or T-Mobile is your preference for iPhone carrier in U.K. In such cases, Hackers come forward and provide tools to unlock iPhone. After the unlock iPhone can be used anywhere around the world. Another solution is to get factory unlocked iPhone which may not be also feasible in many cases.
Breaking:
- ultrasn0w 0.93 has been released by iPhone Dev Team. You can finally unlock iPhone 3.1.3 [05.12.01] on iPhone 3GS and 3G.
- ultrasn0w 0.93 also makes possible to Unlock iOS 4 iPhone 3GS 3G.
Apple does not allow such unlock on their iPhone. They upgrade baseband [which is actually exploited] with release of iPhone firmware and patch any other holes. This baseband firmware remains unlocked until vulnerability is found. The current stable iPhone 3.1.3 with baseband 05.12.01 is also locked for users to date. There has been no tool released although exploit has been found. Sherif Hashim, a baseband hacker, was successful to found an exploit in 05.12.01 which can eventually unlock iPhone 3.1.3. This exploit was handed over to iPhone Dev Team which will release the final product to unlock iPhone 3.1.3 with baseband 05.12.01.
Similar is the case with iPhone 4.0 unlock whose baseband is 05.13.04 although it is still beta. But there is no time left in June 7 when Apple will make a public release of iPhone 4.0 firmware and announcement of iPhone 4. It looks like that unlock iPhone 4.0 will be available as well but after June 7. So the users who have waited so long to unlock iPhone 3.1.3 [05.12.01] and unlock iPhone 4.0 [05.13.04], don’t worry its coming soon. Here is the response of “muscle nerd” to a user asking about iPhone 3.1.3 unlock.
MuscleNerd, member of iPhone Dev Team, again ensures that solutions to Unlock iPhone 3.1.3 [05.12.01] and Unlock iPhone 4.0 [05.13.04] will be availble within this month as Apple releases iPhone 4/HD and 4.0 firmware.
