Those brave souls at xda-developers are at it again. XDA forum member OndraSter has released an Alpha version of an application that reportedly enables pinch to zoom functionality on devices with resistive touch screens, such as the HTC Touch Pro2.
At this point I haven’t been able to make it work on my AT&T Tilt 2, but we are talking about Alpha software; so try at your own risk. The application is tested and should work with Opera 9.5 and 9.7, and Google Maps. Hit up the XDA post for the download. Don’t forget to donate to the project if it strikes your fancy.
