Ultrasn0w 1.2.8, an unofficial carrier unlock for iPhones, has been released by MuscleNerd for iOS 6.1.
As you may have heard, the DMCA exemption that made unlocking handsets legal in U.S, expired on 26th of January, 2013.
However, it is legal to unlock phones purchased prior to the change, so use of Ultrasn0w 1.2.8 is possible on older iPhones without breaking laws, according to iGeeksBlog.
Ultrasn0w 1.2.8 is already available in Cydia, and works on iPhone 4 and iPhone 3GS/3G.
There’s only one baseband supported for iPhone 4; 01.59.00, while the other models support include baseband 05.11.07, 0.5.12.01, 05.13.04, 06.15.00, 04.26.08.
The baseband of old iPhone models can be checked at: Settings > General > About > Modem Firmware.
Developers recommend that those with older basebands not update the baseband while upgrading the firmware to iOS 6.1.
