Hello: my buddy has a t-mobile with everything except the wifi. It shows bars but won't connect when the password's entered. I've searched and seen fixes and talk about bootloaders and upgrading and downgrading it but not a solid answer.
He has a 1.1.3 unlocked through ziphone. Ziphone was used more than once, which I've read causes a bootloader issue. Tried virginizing through ziphine- nothing. Tried the fix in the new iliberty program- nothing

Is there a place in the NYC area that'd be able to fix it?.. How much?

Or does someone have a fix suggestion?
