Hi guys, Got an Iphone 3g 16gb for christmass '08 but it was locked. took it to this place in brighton and they unlocked it for £20 with the 2.2 software. worked absolutely fine, received network and my orange sim card worked fine! Then the 3.0 software was released so i took it back to the place in brighton but they wanted another £20 for just updating the software. so i took into my own hands to try and unlock it myself. so i downloaded Pwnage tool and created an IPSW with the 3.0 software. put the iphone into dfu mode and then restored using the IPSW that i created using Pwnage tool. Phone was unlocked with 3.0 software however now i dont receive any network what-so-ever. I've tried all the resets and everything but nothing seems to work So where did i go wrong?! I have my Iphone with all my apps and all my music but i have to carry around another phone to actually make calls!!! Please can someone help!
