Not sure if this is such a crazy deal but a friend of mine was looking to upgrade to a 8110 and I found this deal for him on WireFly through TechBargains. Essentially the Pearl is free with a new activation and you get a free TrueBlue Bluetooth headset. If you are already under a contract you can renew the contract and get the deal for $50 which is what he did. You just click the “get this phone with a contract extension” on the top of the page.
Let me know if you find a better deal for the AT&T 8110 or 8120!
Follow the directions on TechBargains to get the deal
