Ashley Montanaro has released two small free utilities to help users of the 7650. NameSwap (http://www.allabouter6.com/software/directory/viewsoft.php?id=211) allows you to swap the names of all the contacts on your 7650. Foward (http://www.allabouter6.com/software/directory/viewsoft.php?id=212) allows you to send files you receive via Bluetooth, infrared or e-mail to other people.

Both programs are available from here:
