Could i flash at&t iphone 3 to cricket?

I'm looking at cheap iphones on craigslist and i only see iphone 3 and i know that is old so i was wondering if i could flash that to cricket?

Nope, you can't get the iPhone 3G flashed to Cricket as iPhone 3G are GSM and are not compatible with Cricket which is a CDMA carrier. You can get iPhone 4 which are available CDMA and can get them flashed to Cricket. If you need iPhone flashed to Cricket at cheaper price, mail me to yonoulee@gmx.com
