Is HTC gearing up to release an update to their popular TouchFLO Windows Mobile skin interface? We certainly hope so. These screenshots purportedly depict a refreshed interface, though we can’t tell much from the actual images. The new interface is apparently code-named “Manila”, but that seems that’s about all we can discern. HTC Insider has, however, posted the actual source files, so if you’re feeling a bit adventurous you might want to head on over and give it a shot. If we had to wager a guess, we bet that HTC was preparing a refresh to coincide with the upcoming Windows Mobile 6.1 update, though that’s pure speculation on our part.
