mine is official unlock but jailbreaked. so what you suggest ? restore before update or no need?
thanks!
Yes, your phone will remain unlocked but your jailbreak contents and apps will be gone. You can choose to restore or just update it right away.

Jailbreak phones are safe as well, yellowsn0w ones are not.
However, jailbreak ones need to wait for the release of new jailbreaking tools for 3.0, and if its an unlocked phone, it will stay that way till kingdom comes.
Get your facts right bro, otherwise just refrain from posting la rather than misleading others.
You're the one who needs to get it right.
iPhone 2G (mostly locked units): If jailbreak-ed, contents or apps will be erased and your phone is locked.
iPhone 3G (unofficially unlocked units): If jailbreak-ed, contents or apps will be erased and your phone is locked.
iPhone 3G (officially unlocked units): If jailbreak-ed, contents or apps will be erased but your phone remains unlocked.
