UNLOCKED Blackberry Bold 8900 STRAIGHT SWAP NOT FORSALE... !

I have a blackberry bold 8900 it has a white case at the front and its all black on the back, has a few minor scratches on the front of the phone (not screen). my blackberry is in excellent working condition and it is also unlocked to any network. I am looking to swap it with either, a blackberry bold 9900, a blackberry torch (big one), samsung galaxy S2 or an ipnone 3GS and it must be UNLOCKED to any network. I am not wanting to sell this phone i just want a straight swap!! The reason im wanting to swap my phone is because i just fancy a different phone now, had this blackberry since november last year so fancy something different. I DONT have the charger for this phone because my puppy chewed it and iv not bothered buying another one because ive been using my sisters charger.. they are cheap to buy or you can either use a samsung, some nokias or a blackberry charger for this, maybe others.. please feel free to contact me on 07511292642, no time wasters please..
