Storm owner? Do you find your Storm's display rotates from portrait to landscape or vice-versa when you don't want it to? If so, you'll want to check out Storm Rotation Wizard from Mobireport (developers of Pimp my Pearl and Berry Locator).
For $2.99, this utility allows you to lock the Storm's display in portrait or landscape, or you can choose to leave it on auto-rotate (the way the device is by default). It's simple and it works. The file size is tiny (3k) so it won't crush your memory and it won't drain your battery. Of course this is functionality that should have been built into the Storm's OS for free, but we won't go there. Another new app, StopTilt, offers similar screen control functionality, but lists for $9.95.
