The latest newsletter from Trends Mobile, an Asian-Pacific distributor, revealed that E-TEN glofiish X500 users will be able to upgrade to Windows Mobile 6. Pricing and availability details were not revealed though. Instead, price is TBA. Perhaps they are wisely waiting for E-TEN to officially announce such a move before releasing those details.
If the X500 gets the upgrade, it is likely that a similar ugprade will follow for the M700.
