One feature of the 3.0 firmware that is pretty cool is that you can now have 11 pages of applications on your SpringBoard instead of the previous 9 pages (screenshot below). Which means you can now have 180 applications at your fingertips where previously you could only have 150.

I know some of you probably use Categories so you do not use all 9 pages anyway but, for those people who are not jailbroke…it might be a nice feature of the new firmware. Though, I have found that the more apps I install the slower my iPhone gets but, I might be able to blame that on the jailbroke apps.
