please dont beat me up , but just wanted to ask a couple questions , im sure these answers are buried here somewhere but here goes.... ive got iphone 8gb 1.1.4 and windows vista. is it safe to jailbreak with pwnage , will phone calls and text work all the same , and will I be able to go to 2.0 safely if I decide to next month. I did jailbreak my ipod touch with zphone in the past but hear its not safe on iphone... thank you
