my iphone 3g has been updated to 3.1 and it is official unlock iphone. what should i do now? should i use the "saurik’s new “on file” server " to downgrade my iphone from 3.1 to 3.0. Or i should wait DEV TEAM to release the new pwnage. is it possible to have jailbreak in 3.1? or it is a must to downgrade back to 3.0? thanks for answer me.
