If the radio image in RC30 does anything, it does not change the GSM
bands the radio monitors, as with Stock RC30 and JF1.3, I am unable to
get on AT&T 3g where I know it is available. I am hoping to find a
blob, possibly for an already AT&T device which uses this same radio.
Currently, I am tracking down other deviceswhich use this chipset and
looking for their hacks. I know Moto hackers have what they call 'seam
edits' but I am not sure what exactly that is or if that is what I
want. If anybody has some solutions or wants to join in on this quest,
you are welcome to inform me of your updates =].
