I am coming from Droid Incredible running CM 7.1 on PagePlus for 3 years (Verizon MVNO for those who don't know). So I am familiar with Android ecosystem and rooting.
I am looking to buy Moto X to be used in USA on H2O (AT&T MVNO) because on Pageplus the speed are limited to 3G and most new phones cannot be activated without flashing which I don't want to do.
1) Is there any reason NOT to buy Developer Edition (GSM Networks)? Current price is now the same as AT&T branded version and I am OK with just one color being available.
2) Am I correct in understanding that this version of the phone supports all LTE and HSPA frequencies both for AT&T and TMobile? Quote from the spec:
GSM/GPRS/EDGE - UMTS/HSPA + up to 42 Mbps - 4G LTE
2G/2.5G GSM/GPRS/EDGE bands
3G UMTS bands
850/900/ AWS/1900/2100 MHz with HSPA+ up to 42 Mbps (B5/B8/B4/B2/B1)
4G LTE bands
3) Are there any known issues with Moto X that has not been fixed with software updates yet? I am also considering Moto G which would be good enough for me but it has battery issues ("instant" drops from full charge to 1%) that are now investigated by Motorola but no solution yet. For Moto X so far I only found that some people have small cracks on their cases that are fixed by mailing it for warranty work.
