I have a 1st gen iPhone at 1.1.4, activated, unlocked and jailbroken with software from iphoneunlockuk, which looks like iLiberty +.

Will dev team's much anticipated pwnage take me to 2.0 and leave me activated, unlocked and jailbroken? Or do I need to wait for iLiberty + to upgrade?

Congrats to dev team, sounds like u've done it in no time at all! Awesome.
