Here is my problem,

A couple of days ago i decided to jailbreak my version 1.1.2 iphone and did so successfully. Everything was working fine until today, i was using an application that i got off of the installer app and suddenly my iphone went into recovery mode. So i decided to try to jailbreak it again to see if it would work and everything was working fine until i tried to upgrade it back to 1.1.2 after i installed Oktoprep. I got a message on my iphone saying that i couldnt activate because i didnt have a signal, but i had a signal in the same exact place before this happened. Now i want to get my iphone working on version 1.1.2 with a jailbreak, but cant activate because i apparently have no signal. I dont want to upgrade to 1.1.3 because i dont want to wait for the jailbreak for it. Can anyone help me? Any help would be greatly appreciated, i am trying to get it back to the 1.1.2 jailbreak as soon as possible. Thank You!
