Coming To An iPhone

I have a jailbroken iphone 3G. When I sync with iTunes, the Applications Category seems to be using 2GB, but I only have 10 applications, and they only have a maximum of 10 MB each.

I used to have several cracked apps, buy I deleted them.

Is it possible that those erased apps are still using some of my iPhone disk?

How can I free all that space? Thanks!

Take it back to the store where you brought it. It sound like more than a app problem.
