I still have my old HTC Desire HD (Inspire 4g in the US) running Android 2.3.3. I can handle my whole agenda with that device. It covers all my needs (Besides working as a C.S rep for a M.V.N.O; I also offer tech support to small/mid business for their computer networks and equipment; I am trying to establish a small tech support business on my own).
I do not live in the U. S. and I guess many people that work on C. S. for cellular carries around the world (and U. S carriers that outsource their customer service) follow this website.
Which phone do you have?
