I have a UK Unlocked on 4.1 right now, and I'd like to go to 4.2 (yeah I want print that bad, lol). It's JB'd with SHSH on file. If I upgrade, will the device still be untethered, or using existing methods will I lose my untethered state of jailbreak? On a side note, what does the baseband do to a phone? Even though I don't care about unlock since it's factory unlocked, when I upgraded to 4.1 from 4.0, I preserved the original baseband that came with the phone. I've heard baseband can potentially help with reception issues... true or Apple\AT&T sh#$-spouting? Thanks for the help!
