I've recently got on my hands a verizon branded M7, but I use ATT. The phone came unlocked so I poped my SIM into it and it is working fine. However, I only get EDGE speeds, no 3g (HSDPA).
So I've been searching around and on the CM page, they say that the m7vzw is only capable of HSDPA 1900,2100 Mhz. Seeing as variants are very similar. I was wondering if someone knows if I can flash a radio or something to activate more HSDPA frequencies, or is this hardware bound?
