Hit the jump to learn more about UltraSn0w 1.2.5…

iPhone Dev Team’s iPhone 4, 3G, and 3GS software unlock, now with added PwnApple. Compatible with iPhone 4 baseband 01.59.00 and iPhone 3G/3GS basebands 04.26.08, 05.11.07, 05.12.01, 05.13.04 and 06.15.00! Thanks to @sherif_hashim and @Oranav for contributing baseband crashes.

Supported Baseband

How to: check iPhone baseband

iPhone 3GS: 04.26.08 – 05.11.07 – 05.12.01 – 05.13.04 – 06.15.00
iPhone 4: 01.59.00

IMPORTANT: 3GS old-bootrom users please apply latest redsn0w 0.9.9b9d before installing ultrasn0w compatibility update.

iPhone3GS owners in our comments section below noticed a problem with the untethered jailbreak available for the old-bootrom 3GS. We’ve corrected that problem in 0.9.9b9d. If you have an old-bootrom 3GS and have already used last night’s redsn0w on it, you can re-run it again without losing anything. Just use this new version, go to Extras->IPSW and manually select the 5.0.1 IPSW, then go back and Jailbreak it again (but you can uncheck Cydia because it’s already installed).

use snowbreeze or redsnow to update your firm ware . Don’t update through itune . Itune will update your baseband and you won’t be able to unlock.
