Ok so I got curious today and figured i'd try to upgrade my iPhone to 2.0. heres my situation... unlocked phone using FAN discount through att, the iPhone data plan added to my account (not the iPhone voice plan b/c no discounts on that) i knew upgrading to 2.0 would lock the phone but i was thinking since basically i have a legit iPhone plan i'd try it and try a normal activation through itunes. it caught me. said no discounts are available for the iPhone. had to go through the painful task of reverting back to 1.1.4 and changing the baseloader. oh well...i guess i know now that it will not work and i need to unlock 2.0 before i can use it.
