So, we know there are two model numbers for the iPhone 5 (A1428 and A1429). A1428 is from AT&T and A1429 being from the rest. Does anyone know if there are any hardware differences besides the A1429 having a CDMA chip? We know they use different LTE bands, but is that because of a software/firmware or hardware difference? The bottom line is, will there be a solution where all LTE bands will be accepted.
