Hi all, I just got a brand new Iphone 3gs (week 50 after this boot change). in addition I have a SIM card used as goPhone by AT&T. till today i used an Iphone 3g with the same SIM card and it worked great after I activated it using blackra1n. the thing is, when Im trying to activate the new 3gs phone with blackra1n(BlackSn0w) it does not work and gets no service whats so ever. if Im trying to search for a carrier, i find AT&T and TMOBILE, but when i press them it tells me that "network lost..." but listen to this: when Im using my SIM card from another country i get service and it works great. Please help me... Thanks!!!
