I currently own a 7750, but I have owned the 7230 as well. I got peeved one day I couldn't get signal in Westchester County NY so I just went out and bought a VZW BB, signal has been solid. But I will be going back to T-Mo once the 7100t is released
I own a 6710 (rogers) has worked great in Hawaii, China, India, ireland, scotland, ... will be travelling to Peru this summer ... does someone know if emailing will work there?
