I currently have an iPhone 4 and I'm looking at moving to android and the Device I have been looking at is the MAXX HD. I currently live in the UK but am in the US until February and looking at purchasing one either via Craiglist or straight from Verizon.

Will I be able to use this on a 3G GSM network at home in the UK without any issues, also if the phone is unlocked will I be able to use the phone on a GSM network here in the US when I return, or will I have to use it on Verzion's CDMA network but get a no contact 'prepay' deal?

Many thanks
