The HTC Touch Pro2 has not been forgotten by the Taiwanese manufacturer and they have just released an official system stability update, being the first official update since 2009. Since there are no patch release notes we can't confirm concrete fixes or information, but according to some comments on the article at PocketNow it's a European only patch and fixes the SoD (Sleep of Death) issue reported on the XDA forum.

Let us know should you find anything while/after updating in the comments below.
