Bye bye iPhone.... Nice to meet you

So Finally I return it last night. Not too much trouble but if you probably has to find apple store that close to att store. other wise you are out of network until you find att store to give you your new sim card and activate it.
The process
- Return your iphone along with the sim card. btw I can use iphone sim card in triple band and up cell phone. I just can not use the data service on it. Tried with Sony ericsson K700i and Blackberry 8800.
- Your iPhone sim card will be burned
- You have to go to att store to get new sim card, this may cost you
- att will activate your sim card using your old number

after all that you can change your feature again in att online.
