Resetting memory card password on symbian s40 phones (Java powered)

The easiest thing to do (that many mobile phone users don't know) is to rename the memory card.
 Surprisingly simple isn't it? But how do you rename your memory card?
Here:

 1. Go to the mobile phone Menu/Gallery and then scroll down to the memory card. Just highlight it, do not          open it yet.

 2. Instead, go to Options/ Rename mem. card, enter Select.

 3. Delete the old name bypressing Clear several times until the entry is clear.

 4. Now, type your desired new memory card name and press OK.

 That's it, you can access the memory card again!

 Note: This procedure has been done on a Nokia 6300, which is a S40 series
 phone, with a MicroSD Memory Card. It's up to you to try this with other
phone models.
