I had the problem with the RYP log file maxing out my iPhone 3GS from the Rock app from yesterday.
Everything is working now after spening several hours BUT I had to reinstall all my apps because all the icons was gone from the springboard and the icon cache plist file wasn't there. All the prgrams and data was there just not the springboard icons.

Now my problem is this: when reinstalling the apps through iTunes to get my icons back iTunes doesn't delete the old app files so everyting is on the iphone twice and I can't get the Navigon app onto the phone because there isn't enough space on the phone.

Can anyone tell me which files is safe to delete from the phone using iPhone explorer?
