Hello

I have a 1.1.4 jailbroken/unlocked iPhone. Can I hit the Syncronize button in iTunes, without my phone is being upgraded to 2.0 (and by that locked) ? I know that I'm not supposed to hit the "Upgrade to 2.0 button", but what I'm asking is whether I can syncronize my music and stuff, without it automatically updates the firmware at the same time.

Thanks in advance.
