I am interested in picking up a secondhand phone off of ebay or somewhere, that I can take with me to the lake, beach, construction sites, etc. I am new to AT&T and am not familiar with their phones, also I plan on swapping SIM's so I need it to be AT&T compatible. I would like to pick up something I guess that has the most bang for the buck - not too expensive but will still get a lot of different things done. Anyone have some recommendations? I was thinking about a RAZR just wanted some thoughts from people with some experience. Thanks.
