My Nokia C3 is missing apps Communites, OVI, Opera and Mail. And the mobile card’s memory is gone too. What has happened?
remove memory card, restart phone?
Perform hard reset of your phone -
Hard reset should work.
it could be firmware problem. try resetting the device to factory settings.
if to no avail, reinstall the firmware.
that should work.
Maybe your pocket contents conspired to delete them. Mine has been known to sent cryptic e-mails and make calls unless I lock the keypad.
I once had a Nokia that was infected with a virus that used to do the same even if the keypad was locked. Got that virus from Bluetooth content from a friend who didn't even know that his phone was looking for other devices to spread the virus...
