Is there a way to jailbreak my iPhone (firmware is 3.1.3)? My friend jailbroke his using blackra1n, but when I checked on the blackra1n website I found out that there isn't a jailbreak for 3.1.3 yet. So I googled it, and sn0wbreeze seems to have one for the 3.1.3 firmware. Anyone have any experience with this? Is it as good or reliable as blackra1n if not better? Any help is appreciated, I just want to know what software I need to jailbreak my iPhone on firmware 3.1.3 (7e18) Thanks!
