iPhone 3GS - Unlocked/Jailbroken

[heredia21]

I have unlocked and jailbroken my Iphone 3g s. The only way to fix a signal fading on T-Mobile is to insert a ATT Sim. Does anyone know a fix for this so I wouldnt have to do that? After every reboot I get a signal fade with my T-Mobile sim card. unless I have att sim.

I'm not sure if this will fix it, but it's a suggestion that wouldn't hurt trying. Whenever you get signal fades, enable Airplane mode and then disable it.
