Hi everyone!!! I got an IPhone 1.0.2 a while ago and always wanted to upgrade...But I was always to scared to transform it in an expensive brick!!! I would like to know what I should do to safely and easily(I have no hacking skills) upgrade my phone!!! My IPhone is firmware 1.0.2 my modem firmware is 03.14.08_G I don't know how it got unlock but It's one of the old methods I live in Canada and have no at&t sim card(Could it cause problems for activation???) I use a PC not a mac!! I just downloaded ZiPhone Gui v.3.0 (I think that it could help but I think I need to virginize my Phone first...right?) thx for your help!!!!
