I just jailbroke my iphone 3gs. It was on at &t and I finally got it to say the carrier is t mobile. My firmware is 6.1.3 and my baseband is 06.15.00. I guess it is a tethered jailbreak because I can only open cydia if I use just boot in redsnow (doesn't work if I just start it myself). When I use just boot it says searching and then no service on and off. I have installed ultrasnow, but I still am unable to get any service. Any suggestions? Thanks.

May I suggest downgrading your baseband via redsn0w version 05.13.04? It'll improve your GPS services on your phone, if nothing else. You'll still be tethered on the jailbreak, but hopefully will have a more stable cellular performance. First, download the iOS 6.0 IPSW for the iPhone 3GS and select that IPSW via Extras -> Select IPSW then go to Jailbreak -> DFU mode -> only check the "Downgrade Baseband box." Let redsn0w work its magic, then your phone will reboot. You'll need to run the "Just Boot" again to open Cydia, but once you've done that you should be golden.

Jailbreaking doesn't affect what version of iOS is installed on your phone--it just removes many of Apple's restrictions on a particular version of firmware. If redsn0w can't find SHSH blobs for any other versions of iOS for your phone, then you won't be able to restore to those versions of iOS and have an untethered jailbreak (thus, you're stuck on 6.1.3).

To be honest, I suspect your phone has a hardware issue with the baseband chip and/or antenna. Ultrasn0w 1.2.8 is supposed to work on 6.1.3, so I doubt that's the problem (but you can try uninstalling and reinstalling the ultrasn0w software if you'd like).
