This video will show you how, for $3 plus tax, you can create a rigid hardcover protective shell case for your smartphone in order to protect its touchscreen and front-facing buttons, provided that its dimensions are similar to or smaller than those of the iPhone 4. This method has been proven to work nicely with the following mobile handsets:
Samsung Galaxy 3 GT-I5800D Apollo
Samsung Galaxy Gio GT-S5660M
Lg Optimus One LGP500H
Apple iPod Touch Fourth (4th) Generation
Note that this case solution is intentionally magnet-free (please do a search on Google for 'magnet dangerous iphone' before considering a case with magnetic clasps for your smartphone)
