I know this is probably a newb question, but I wanted to know if it's possible to upgrade to 1.1.4 after using effeXTC's AT&T user jailbreak guide. I don't want to downgrade my bootloader or anything. Any help would be greatly appreciated. (btw I've noticed that effeXTC guide is nothing but questions now and no reply's back to most. So I decided to make a new thread. Hope that's ok.)
