Eten announce on their website that owners of the Glofiish X500 can now download and install a new ROM image that will upgrade them from Windows Mobile 5.0 to Windows Mobile 6.
As with all ROM upgrades, please follow the instructions to the letter as you do not want to brick the device by having the battery go flat or the laptop you might be using to flash it go into hibernation half way through the process!!
If this works like the HTC ROM upgrades, the machine is wiped clean, so sync all your contacts and back up images and documents to a memory card.
Finally remember that you will need ActiveSync 4.5 to talk to a WM6 device, not version 4.2 or whatever came with the Eten. This is free to download from the Microsoft website

"E-TEN, on May 14, announced the delivery of three language-localized ROM updates that allow owners of Glofiish X500 and M700 Pocket PC Phones to upgrade their devices to Windows MobileR 6. The updates are available for owners of English, Russian, and French devices. Further languages will be available for M700 devices at a later date.
Owners wishing to upgrade their Glofiish Pocket PC Phone to Windows MobileR 6 should visit www.glofiish.com. There they will find instructions on how to register for the free download. Owners will need to supply their device's IMEI number (located beneath the battery) and a valid email address to complete the process.
This optional upgrade is offered as a value-added service for Glofiish customers wanting to enjoy the latest mobile platform, E-TEN noted. Customers who do not wish to upgrade may continue to use the default software platform of their device.
E-TEN highlighted that the benefits of Windows MobileR 6 include a new user-interface, optimizations to make better use of hardware resources, and updated software, including new versions of the Mobile Office suite."
