Currently have a BB 8310 Curve, will be switching to a 3G iPhone when available (I'm not camping, so it's not going to be 7/11). Won't duplicate what many have already written (all good stuff) although I will add that I'm in the "need Exchange sync" capability. My cheap arse company has chopped off BES access to only top brass due to costs (BES ain't cheap). Not being high enough on the totem pole to rate access, I'm stuck using BIS and manually syncing with Outlook on the desktop via USB. Which absolutely sucks.
I've done WinBlowz previously and will never own/use/pay money for WinMo anything as long as I live. Having said that, ActiveSync is the one part of WinBlowz that works like a charm so when that became announced for the software upgrade, along with 3G and GPS, that's all I needed.
Great smartphone round robin over on crackberry.com and it provides excellent perspective for each platform & phone. Best line from there is that the "Curve is the anti-iPhone" and that's true in many ways. A lot of the Bold versus 3G iPhone is going to come down to user preference I think. If you want a physical keyboard or need a CDMA flavor, then the Bold will be your best option (I'm assuming VZW will get a BB Bold version 12-18 months after ATT as usual).
Summary - Curve has been a very worthy road warrior and is the current king of mobile email & messaging. But the browser is a joke, Operamini only helps a little, the screen pales compared to the iPhone, it desperately needs 3G and I wanted GPS over wi-fi (although I now realize I want both). The OS is in serious need of an overhaul. And I have nothing to hold me back from an iPhone now so I'm getting one 'cause it is just the coolest piece of technology I've ever seen. And, like others above, the potential of this platform is going to take off with 3rd party apps coming to the party IMHO. Try getting an OS update for BB out of AT&T!
Also - what's so great about a smartphone in the first place? Phone? Music? Email & messaging on the fly? Internet Access with a real browser anywhere? Games? Watch a movie while stuck on a plane back in cattle car section? iPhone does all of that and better than any other device currently. And is easily the coolest design. As frequently in the past - Apple just turned the industry on it's head and over the past 12 months, you've seen every other cellular handset manufacturer scrambling like heck to try and catch up. Apple left out a lot of stuff they should have included this time around but overall, it's just drool worthy.
