Microsoft plans to release at least one more Windows Mobile 6 version to tide users over until a more meaningful upgrade, a leak says today. The company is purportedly so disappointed with Windows Mobile 6.5 sales since launch that the company is rolling out a 6.6 update in February. It would primarily add native support for capacitive touchscreens, which would give it much more finger-friendly input than the resistive-only 6.5.
