Right, sorry back pedal but I'm no iPhone genius
I'm desperate to upgrade to the new 3.0 software on my iPhone 3G
It is currently jailbroken and unlocked (to use on three network) using yellowsn0w
Can I safely upgrade via iTunes and use Redsn0w? only this bit on the Dev Blog is bugging me....
- GOLDEN RULE: If you are using a 3G iPhone with yellowsn0w and rely on yellowsn0w to obtain cellular service, then you should NOT use redsn0w right now. Ultrasn0w (the 3G carrier unlock) is not included with this release and therefore your baseband will be locked and unable to use an operator other than the official one it was bought for. UltraSn0w will be released via APT (cydia and icy) soon. If you have an original iPhone (1st generation) then 3.0 carrier unlock works with this redsn0w release.
Please help!
