I had the 8330 and really liked it. Now I have the Tour 9630 which is similar to the 8330 just amped up. The keyboard is easier and faster to type on. The camera is 3.2mp, and it has more memory than the Curve. I had issues initially with the trackball but that has been taken care of. There is a new Tour on the horizon that uses the trackpad instead of the trackball, I think that would be a good way to go.
Wifi for me is not an issue. We have excellent 3G coverage here in Alberta so I don't care about wifi. The BB browser stinks, so I downloaded Opera Mini for free. It works for what I need it for. BB Messenger is real handy. I don't think I would even consider an iPhone until they come out with something similar.
As for the problems the one poster was having. You can download Quickpull for free. It simulates a battery pull and you can schedule it to do so when your sleeping. I seldom have to reboot my BB.
