Note this as a strange, but useful app. See Through Messaging for Windows Phone allows the user to create SMS messages and emails on an overlay on top of a real time view of what's behind your handset via the camera. Basically, you can type while looking through your phone.
We've seen this before with TransparentTXT, which runs for $2.49, but See Through Messaging goes for the low, low price of free. (And of course LG users have had 'Look N Type' for free for ages through their app store).
Should you find yourself on the move while contacting other people, See Through Message could save you some embarrassment when not paying attention to what's in front of you. Only downside we noticed was there's not auto-correct nor word suggestions, which means your texting perambulations will be filled with errors, unless you're careful.
Download See Through Messaging from the Marketplace for nothing at all.
