Jailbreak problem, need help
Okay, so I had a jailbroken iphone 3G with 3.1.3. I decided to upgrade to 4.2.1 but now things dont seem like I actually upgraded. Was there something I was supposed to do before I upgraded my jailbroken 3.1.3? If so, what can I do now to fix it?? I dont have a background option for behind my apps, no spotlight option. Settings confirms Version 4.2.1 (8C148) with Modem Firmware 05.15.04. Any help would be greatly appreciated. Thank you.
