Alright, I'm entirely new to jailbreaking, but my regular phone is going to be in service for a while so I'm switching over to an old iPhone. I jailbroke my 3GS using Absinte 2.0.4 and everything went smoothly. The only problem now is that I can't figure out how to get my T-Mobile service on it. I put the sim in the slot, it fit no problem, but I'm getting the SIM Failure error. I've tried resetting it, going into airplane mode, and powering off and back on along with taking the SIM card out and putting it back in a few times. Like I said, I'm super new to this. I'm sure there's an answer for this and I'm just not seeing it, but I could really use any help you're willing to give. Thanks!
edit. alright. I just put in ultasn0w. realizing that it was probably needed. But it just says Searching... instead of T-Mobile. Am I getting there?
