S abut tw days ag I had 3.0 jb and wanted some new apps so tried sn0wbreeze on my launch day 3gs on windows. Didnt work was stuck in recvery mode. So upgraded to 3.1.3 then downgraded to 3.1.2 (as saurik has shsh hashes - edited the host file as requested) and jailbroke with redsnow. Jb worked iphone loaded up but no cell signal - it didnt get activated. upgraded to 3.1.3 then downgraded to 3.1.2 again and jail broke with blackra1n. Same thing no cell signal. I have pretty much given up hope for the time being that anyone can help with my problem clearly and concisely.
