hey guys I'm new so and fairly green when it comes to jailbreaking/unlocking so bare with me. Ill keep it simple. My set up is a 3G version: 3.1.3 with 05.13.04 baseband. Its jailbroken, I've installed ultrasnow, turned off 3g, put in tmobile sim ($50 unlimited plan). Problem is I get "No Service" still. What could possibly be wrong? At this point im will to just flush the whole thing and restore, but I'm figured that if anyone could help they would be here so please fill me in and lemme know if more info is needed. thanks
