I've been on MetroPCS for a while and they just boosted the 3G coverage and they are rolling out the 4G in metro areas too ... BUT they don't have the latest and best phones? So, what's everyone got for a SmartPhone? You have iPhone or Android or something else? Do you surf the web with it, or do you prefer to download apps? Do you get on GMTC with your SmartPhone? I'm looking at getting the Thunderbolt on Verizon, but it's a big jump in cost for me. Thoughts? I know one guy who has it and he loves it.
