OK I FAILED CELL PHONE IN SCHOOL. On my insurance post(which the replies were helpful) Some of you bought phones off ebay, amazon and such, smart phone types. Here is the question: Ho do you buy them and have them work on your carrier, us cell, verison and so on. (compatibility)? How do you keep your number? I agree $900 is to much for one but is buying one on line then going to the cell phone out fit with it (to make it work) similar to buying a John Deere item online and going to the dealer to get it fixed? I was told they need to be programed to you carrier an att will not work on sprint etc. And does cell phone store have any obligation to say one you bought on evil bay? THANK CONFUSED
