i hate the additional document and data thats been added on my storage while browsing Facebook on iPhone. It seems there is no option to delete it but to uninstall the program. FB is just only 16mB and now it burst to 98mb just browsing on it...and still its growing up everytime you browse. How to Remove "Other" Data from Your iPhone | Mac|Life but when im using facebook on safari, it doesnt eat any memory at all, only the facebook iphone app does. its just not only FB, but also in the other apps! i hope apple can resolve this...its annoying to delete and install the apps again just to clear the consumed space... it seems here have the option to delete: iOS 5 Offers A New Way to Manage Storage | LEi Mobile or why they removed that options from the IOS 5 beta!!! arggh!!!! we need it!!!!!!!
