Apparently Phone 7 is so specialized and so proprietary that only phones released from this point on can even dabble in the newest operating system. The news comes from a recent article in enthusiast publication APC Mag.
In an article there, Microsoft's general manager for mobile communications in the Asia-Pacific region Natasha Kwan was quoted as saying that current Windows Mobile users will only be able to upgrade to a light version of 7. The current OS is Windows Mobile 6.5, and when Windows Phone 7 launches, existing phones will get minor tweaks.
The new OS has a laundry list of mandates, from a strong processor to a requirement that there be three soft buttons.
Regardless of the unfortunate news for Mobile 6.5 users, hype remains high for Microsoft's new mobile platform, which was unveiled at last month's Mobile World Congress. It is set to be available in the latter half of 2010.
