I travel a lot between the USA and Europe, in each place for up to 9 months at a time. I have always had unlocked GSM phones that supported the standard Euroepean 2G & USA 2G bands. Am now looking for a Android phone for heavy data use and am dissapointed that despite the fact that my phone would be carrier unlocked, I will be forced into using AT&T in the USA because T-Mobile does not use the European 3G frequency. LTE is coming soon though. Been reading about it and confused on how it will handle different legacy network types (gsm/cdma) and bands. Can someone offer a bit of detail? Will this solve issues with incompatible GSM bands (the idea being that a LTE phone is backwards compatible across all legacy networks)? For instance, would a Verizon LTE phone work on GSM networks? A bit of clarity would help guide my planning.
