I was searching for the way for resetting the wordpress password better than the PhpMyAdmin Pass change method, and founded at http://blog.skdev.net where Salman Mehmood have created a script for resetting the WordPress password.
You can download the script here.

Installation Guide:
Step 1:
Download this file “WordPress: Reset Admin Password Script“, Extract & Upload it in your WordPress directory (it must share the same folder with wp-config.php).
Step 2):
Open it in your browser (ex: http://yoursite.com/wordpress/reset_pass.php)%5Bad#ad-2%5D
Click on your Username, enter a new password and click submit, your password is updated. You can login with your new password now.

For security reasons it is advised to either delete OR rename reset_pass.php on your server.
