I saw a good range of cell phone pda on sale at ebay store but am not quiet well versed with knowledge about the pda cell phones. I also got the information that its a very old technology on which they are based and at present they are quiet outdated. Do anyone has got some nice information on this technology and what you feel on pda being called outdated.As am based in Miami, Florida I want to have your suggestions on making purchase of a cell phone pda since they are available at quiet cheaper prices.
