E-TEN has released the Windows Mobile 6 Professional upgrades that it had announced back in March for the Glofiish X500 and M700.
The upgrades are available in English, French and Russian. Your device needs to be registered with E-TEN and you will need an Action Key (sent to you via email) as well as your IMEI number.
Note: These ROM updates will wipe all your programs and data from your devices so be sure to have backups of everything before you proceed.
