You may remember Wondows Mobile smartphone which is produced two years ago, Toshiba TG-01. This turns out older smartphones can use the Windows 7 Phone.
It is actually quite reasonable because the specifications are very supportive of the 1GHz processor and 256MB RAM. First phone using Windows Mobile 6.1, and can update to Windows Mobile 6.5. Apparently there are now trying to use Windows 7 Phone and succeed.

It is not known the purpose of the use of WP7 on this smartphone, whether for internal testing or Toshiba that are being experimented with WP7? Of course not everything goes smoothly, it was reported that the camera does not work, so pinch to zoom and matters related to multitouch, because Toshiba TG-01 still uses a resistive display types.
