Background: thewalletlist.com is a sort of bitcoin address "shortener" except the key is your email address(es).
There is now an Android widget that helps you keep tabs on your thewalletlist.com addresses. Basically, it just sits there looking green unless it detects that your address has changed. The development was spurred by a discussion here on the forums about the security of bitcoin address shorteners, and how they are susceptible to man-in-the-middle attacks and such.
The widget doesn't "solve" MITM attacks per-se, but it does at least give you a simple way to monitor the status of your own addresses. With the widget, you can e.g. easily verify that your address is still correct just before telling someone to refer to it.
The widget is available from the app store as "the wallet list".
