Well good news for you!
How does a FREE Blackberry Bold 9700 sound? No Contract extensions, nothing. You just handle the shipping and your set! I just received mine yesterday and I have to say I love it. A good friend of mine Dom has done the same thing since I told him about it and his phone is on the way!
Pretty much this is because T-Mobile discontinued the blackberry 8900 device. All you have to do is call T-Mobile and explain to them that you are having problems with the trackball, convenience keys, or whatever (nothing that would be insanely unfixable) and they will tell you that you are able to get the 9700 instead! The only catch here is, is that your phone MUST be still under the 1 year factory warrantee, and you must make sure that you have no water or physical damage to the phone or else they will charge 100.00 to your account for the damaged device. Either way, $100 for a bold with no contract extension is pretty sweet.
Please note that I take no responsibility in any changes made to your account or anything that goes wrong with this transaction, this is just a simple HEADS UP, GET A FREE BOLD that I felt I would share with my visitors.
If you end up doing it and getting your bold, comment on this post and vouch for others to do it!
