Looking for a cheap Blackberry. Basically I've got a HTC that's fucked and sick of it so I'm looking to buy a Blackberry and try that out until my upgrade is through and I'll try an Iphone (so I can pretty much try them all). I'm currently on T-mobile so I need to get one that can either be unlocked or just buy one from T-mobile. Anyone got any ideas where I can get a cheap one? Don't mind if it's one of the older ones, as long as it's not really old.
