Sn0wbreeze 3.1.3 for Windows brings jailbreak for iPhone 2G, 3G and iPhone 3GS (older bootroms only) which can preserve your older baseband while upgrading you to the latest iPhone OS 3.1.3 firmware. This effectively means that once yu jailbreak using Sn0wbreeze, you can also unlock your iPhone 3G and 3GS using the latest version of ultrasn0w (for 04.26.08 baseband) or blacksn0w (for 05.11.07 baseband) as they both are compatible to work with the respective older baseband versions.

  1. Raju, It is not clear to me from your post whether Ultrasnow will unlock a once unlocked 3G iPhone on which I installed 3.1.3 which had the effect of nullifying the unlock. In effect, I now have a locked 3.1.3 3G phone. Will Ultrasnow or anything else currently available unlock it?
