I currently don't have a phone and am I am thinking about getting an Android and am leaning towards the EVO because it seems to be currently the most powerful and Sprint is the cheapest in my area. I am not opposed to the Droid X but Verizon is a little more expensive and this would be more of a toy/gadget than anything else so the cheaper the better. Probably like most I don't want to be locked in a contract if I can help it. What does an unlocked phone get you? If I bought an unlocked EVO off ebay or wherever can I use it on any carrier and avoid getting a contract? So would I be able to take my unlocked EVO and go to Sprint and get a contract? Can unlocked phones have their OS upgraded and still work on carriers? So could I upgrade to 2.2 Froyo and still have a working cell phone? What features do I lose getting an unlocked phone? Thanks for any help.
