  • Should I get a Blackberry Bold or iPhone 4S? I'm going to be getting a new phone soon and I can't decide. Should I get the Blackberry Bold 9900 (which I would prefer because of the physical keyboard) or the iPhone 4S? Now the thing is, I currently have a 2nd generation iPod Touch and it's pretty beat up and glitches a lot, so I'm in need of a new one. So what would be the better option, buying a Blackberry and a new iPod, or just getting an iPhone even though I find typing on a touch screen very annoying?
