I have had the 3G since about October last year. I was happy at first, but after a couple of months or so the scroll pad went, the scroll pad was also dogy when the weather was windy. It scrolls up/down on it's own, and can only be used out of direct sunlight (which makes it go haywire- typing weird symbols and scrolling all over). Putting my shirt over my thumb stops most of the scrolling issues.The browser is really bad, and crashes all the time. The system seems to have little-to-no RAM, so apps run slow or freeze. (Selection isn't that great, either). The camera is bad unless in daylight. But then the zoom goes crazy because of the scroll issue, so it's hard to take a photo. Inside, pictures are pretty grainy, and very low saturation.
The battery when i first got it lasted about 3 days for me, but then months later it only last a day if lucky, However, it does shut itself off lately, and will not turn on until it is plugged in... Even if it was at half battery. Overall, I'm happy with BBM and texting layout. But those are on all blackberry phones.
