There’s a latest application out in the marketplace for HTC-HD2 mobile named ZOOOMER

REQUIREMENTS :
Windows Mobile 6.5, .NET CF 2 or superior

What does this app do?

Zooomer allows “touch to zoom” in the programs you desire. The software scans all .exe files that are accessible on the mechanism. All you require to do is just choose the application you desire to be zoom enabled and then perform a soft rearrange – here you go: the exe is enabled for touch to zoom! For the time being, only consumer installed (and some few fixed) applications can be “zooom-enabled”.
