either the blackberry bold or the blackberry torch OR the blackberry curve any colour!
If your Blackberry 8707v is registered for a Blackberry service, then you should be able to.
The BlackBerry Bold should be able to use BlackBerry Messenger (BBM). It's for BlackBerry OS 5 or newer.

Yes, if you have enough cash, you should go for the Blackberry phone because of the features that it has.
Personal choice, I would recommend the curve.
Well if you're a good person with touch screens you should probably buy an iPhone, but some BlackBerry's have a touch screen as well, so that does NOT mean you SHOULDN'T buy a BlackBerry!...But for me you should buy and iPhone! They are MUCH better looking than the BlackBerry 9700! Trust me!
Any of the major cellular companies' SIM card should fit into a blackberry. After you have bought a SIM card from a cellular company, all you should have to do is place it into the blackberry and activate it.
