Ok i Have a jailbroken iPhone 3GS on 4.1 History: My dad and i exhanged cellphones i gave him my samsung solstice and he gave me his iphone(unjailbroken). He called at&t and made my data unlimited. Every time i used the internet over 3G it said that i couldn't activate my data plan. So...I jailbroke the iPhone with limera1n, i had it for like 3 days without using the internet because of the message still appearing. I decided to google a little about it and got this site: www.unlockit.co.nz I installed it and "succesfully" could navigate without that message and at the third day at&t automatically change my plan to 2GB plan, in which i had unlimited data. I called my dad and he told me that they know that you hacked your phone. They will charge me for every thing that wasn't in your plan and told me that you needed to hack it with his(my dad`s) sim in it first and then use mine.(my sim) obviously he said this very mad!
