Looks like AT&T has outdone itself. If you need a replacement phone for your AT&T\Cingular line, grab the Sony Ericsson J220a on GoPhone (make sure to activate it though). It's all of $9.99...and no, I'm not kidding...if AT&T offered this phone in my area I'd already have bought it to review.
On the Tracfone side of things, the LG 3280 is...until at least the end of July...$20 at Family Dollar stores. My advice: pick it up already! Granted, it may not have quite the reception of the Nokia 2126i but it is SIngleRate, it is a flip phone and it's not a piece of junk, so it's definately worth $20.
