Are you a veteran BlackBerry users that went Droid or iPhone only to have regret the change? I may have a cure for you... In addition to the recent T-Mobile 2011 roadmap leak which reveals that they will be carrying three of the upcoming BlackBerry devices - T-Mobile has also launched a new Trade-In program which allows you to trade your device for money that can be used toward the purchase of a new handset. See the solution? Get rid of that old junkie Droid or iPhone and get yourself a fresh new BlackBerry and rekindle your BlackBerry loyalty!

T-Mobile will give you up to $300 credit for your device, regardless of brand name or which carrier it is on. The minimum criteria is that the phone needs to be fully functional, have an intact and working display and be free of liquid damage or corrosion.

You can take advantage of this offer by visiting any T-Mobile retail store. A T-Mobile representative will determine the trade-in value for your device and a check for the quoted amount will be given to you via a mail-in rebate process.
To check the estimated value of your old phone in advance, just visit My Trade Ins | T-Mobile.
