Ronen at BerryReview makes a good point when he links to a BlackBerry comparison video: You can’t go into a store and compare various BlackBerry models side by side. Well, that is, unless it’s the BlackBerry Store. Go to a T-Mobile retail outlet and you’ll have the Curve 8900, Curve 8520, and then some older Pearls and Curves. Go to AT&T and you’ll see the Bold, Curve 8900, and some other models. Verizon’s (and Sprint) the only place for the Tour, so you can’t compare it side by side with a Bold. That’s why I’m also linking to this video. It’s a good look at the various BlackBerry models out there right now, and it can be a good starting point when making a decision about your next BlackBerry purchase.
