I'm happy with my T-Mobile one. I am an avid VZW customer for phones. I was skeptical about the T-Mobile Network since I wanted the data plan. It's not VZW good but it aint bad either. I have 3g service most places I go and they are rolling out real 4g next year. I think you will be happy. Just so you know, T-Mobile, like all Tabs, have 2gb internal OS memory as well... they just have the extra 16gb of Internal SD card. They even call it Internal SD too. I don't think you would run out of memory as long as you have enough storage card capacity. My Incredible only has 2gb of internal as well but has the 8gb internal sd so to speak. Hope this helps.
