SPB Software has updated their Windows Mobile user interface, Mobile Shell, and inches ever so slightly towards the anticipated release of Mobile Shell 5.0 (which seems to have gone missing).

The update, version 3.5.5 adds support for 320x480 resolution, fixes bugs related to the Task Widget and other routine performance fixes. If you've recently purchased Mobile Shell and are worried about the cost to upgrade, SPB offers free upgrades for all registered Mobile Shell 3.x users. Simply download the trial version and install it over your existing version.

Mobile Shell 3.5.5 is running $29.95 and is available over at the WMExperts.com App Store.
