Sn0wbreeze 3.1.3 is now available for download which can jailbreak iPhone 2G, 3G and iPhone 3GS (old bootrom only) on iPhone OS 3.1.3. We have already published a detailed guide on how to jailbreak using Sn0wbreeze and unlock using ultrasn0w. Ultrasn0w unlock is for iPhones with baseband 04.26.08 baseband. If you are on 05.11.07 baseband, then you may use Geohot’s blacksn0w unlock which was released last year with blackra1n.
