gud am... pano mag delete all ng contacts sa iphone apple?? help po

Hi, I don't have an iphone but nilalaro ko ang ipod touch ng kaibigan ko. Simple, delete your itunes back-up, delete your contacts in iphone, then resynch in itunes.

Here are 4 other ways to delete all of your contacts in iphone adress book.

A. Easiest. Jailbreak your iphone. A simple web jailbreak/spirit will do. Tapos sa cydia, hanapin mo yung apps na pwedeng mag-erase ng contacts, example ContactEraser. Ito yung mga apps na kayang maka-access ng file system.

b. Open Adress Book in pc, type wab.exe. Once the windows contacts are here, just select the contacts and click the delete. On itunes, make sure that in ''info'' tab, the contacts are synched with windows contacts. Synch again, it will delete.

c. Harder. Go to iTunes menu>Edit>Preferences, in the windows that open up, click the last tab named 'Synching', at press button with 'Reset Synch History'. It will erase your last synch.

d. Hardest. Create 2 empty slots on your windows desktop, and name it to AddressBookImages.sqlite.db and AddressBook.sqlite.db. Copy/overwrite these empty files into ''var/root/Library/AdressBook'', using iBrickr. Reset your phone.
