Deleted Phone Memory Files: I had some space issues so I had to delete some files to create space, in the process I guess I deleted some system files. After the delete, I can not start most of the installed programs (even those installed on the memory card).I cannot access my profiles even though the icon is still there. Most of the phone's programs don't work even though their Icons still display. Please how do I solve this problem?

there are many free data and file recovery programs on the web
you could retreive themif you have not written or downloaded any and saved more to your hard drivehttp://majorgeeks.com/Free_File_Recovery_d6792.html

It will even bring back files that have been deleted from your iPod, or by bugs, crashes and viruses!

NTFS Undelete is free software that allows you to recover deleted files. It recovers files directly from hard drive, and it will work even if you empty Recycle Bin.
Before downloading NTFS Undelete, please consider the following:
When you delete a file, its content physically remains intact on the media, but the occupied space becomes marked as free. Next file saved to the disk may overwrite the contents of the deleted file.
It is very important to make sure that no application writes to the drive or partition where deleted file is located since every new file (even a small one) may overwrite the deleted file.


hope this helps you
