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).
