new iphone need assistance please
ok first off hi as im new to the forums.
right my mate bought an iphone in january and had it hacked by them to work on orange, then he bought a new orange iphone and gave me his old one (which he didnt use for mnths). so the problem is i am on o2. I need to know how and if i can jail break it so i can use it with my o2 sim card. below are some details regardning versions on the phone.
version :2.1 (5f136)
modem fimware 02.11.07
i have a feeling it has been jail break before as i have cydia in the icons on the front screen. the hack the company used for my mate was a hardware chip adapter on his sim. this doesnt work on mine.
any idea what i can do to resolve this please.
