So here's the stats: Brand new Iphone 3gs(not refurbished) Came from iphone store factory unlocked already New boot rom on 5.1.1 version 5.16.05 When I got the phone I went through the set up screens,bypassed them by doing the emergancy call trick. When I got to the main screen I inserted my TMOBILE sim card and phone worked fine. I then jailbroke it.All good so far. Then after a week,the phone started acting weird so I turned it on then off.Problem,It's now searching for a signal when I have the sim in.The wifi has always been fine. I tried installing ultrasn0w fixer and then ultrasn0w to fix it,no dice. 3g has almost always been off.Tried turning on and off airplane mode.Still no go. Please help me get this to work again!! I've read some people saying you can't do it on this baseband but I know for a fact it does.Worked on 2 iphones I got from them unlocked. Please Help!!
