I have been using Squid in order to see what programs I had installed which failed. It seems that my iPhone has stored the installer files that are related to the applications that were unsuccessfully installed. I have only the bare minimum installed, yet my iPhone's disk space is full.

Does anyone know of a method to clear my iPhone's "cache", per say?

I am unable to installed any applications due to the fact that the disk space is full.

Any help is appreciated
