After releasing PwnageTool for Mac earlier iPhone Dev Team has released Redsn0w to allow users to flash their iPhone 3GS and iPhone 3G with iPadâ€™s exploitable 06.15.00 baseband so that they can use Ultrasn0w 1.2 to unlock their iPhone.
Apple had patched the exploit that allowed users to unlock their iPhone in iOS 4.1 released on September 8 so it has been a long wait for users who wanted to software unlock their iPhone to use it with any carrier.
Ultrasn0w For iPhone 3GS, iPhone 3G Will Unlock All Basebands, Including iOS 4.2.1 Baseband 05.15.04
Before they go on to explain the current situation, they have advised users to avoid updating to iOS 4.2.1 until they release tools for iOS 4.2.1.
There is finally some good news for iPhone users who want to unlock their iPhone.
iPhone developer and hacker, Sherif Hasim had figured out an easy way to activate iPhone 4, iPhone 3GS and iPhone 3G without needing the official iPhone carrier SIM.
He had discovered that using any phonebook SIM card it was possible to activate your iPhone.
He has just reported that Apple has fixed the bug, which allowed activation using any phonebook SIM.
Apple is expected to release iOS 4.1 sometime today.
iOS 4.1 includes fix for the proximity sensor, Bluetooth and iPhone 3G performance problems and some major features such as HDR photos, HD video upload, ability to buy TV show rentals and Game Center, Appleâ€™s social gaming network.
