Motorola MPx220

Also the Mpx220 is due to come out around Dec 15-20 ( @ least thats what the clerk told me)... Another question If I were to buy the phone from another website such as (letstalk.com...or 1800mobiles.com) will I still be able to exchange the old version of the mpx220 for the updated one for free? Also what does cingular mean by 1MB of web.. can we pass that easily, and if so can you give an example,please?..thnx..
