Removing unwated themes
Sometimes, it might happen that you want to uninstall a theme that you didn't like after all, but the theme denies being uninstalled. This is something that might happen and it actually consists of a s60 bug.
You don't have to throw your mobile away or to panic... there is a solution!!! The only thing you have to do is to open your memory card with your computer (either by connecting your device with your pc, or by reading the card through a card reader).
Once you have plugged your memory card in your computer, you can handle your memory card like any other storage device (hard disc, usb flash stick, etc). Now, the next step is to open the cards' directory and browse to private10207114import.
Easy stuff... Now, browse through the folders until you find the one that contains the theme you want to uninstall but it denies! Usually, you will understand the correct folder from the filenames of its containts.
Since you have found the correct folder, just delete all of its containts, but not the folder itself. Put the card back to your mobile phone, open it and voila.... no more unwanted themes!!!
