Just a mention about a bug we ran into with the HTC Touch 2. When download a cab file in Internet Explorer it renames the file from .cab to .tsk. Obviously failing to install it once downloaded. (.tsk files are the new theme-files from Microsoft)

Apparently the bug is specific for HTC Touch 2, and there is an upgrade for the phone available.
