Radio Issues...I think...

[edufur]

what do you mean that you "swapped" esns? I dont think that is possible. And it sounds like your phone is suffering from an identity crisis. So when you load the stock rom, what bootloader version do you wind up with? and what PRL? have you tried calling sprint support to FLAG for auto prl? maybe your manual load didnt actually take properly. there is a wide range of possibilities. Stick with the stock radio though... 1.27... believe me, I have played with them all and you dont want those problems.
