Really, that sliver inside is probably even smaller...
I’m not sure how many other Tamagotchi fans have Blackberries and vice versa, but I’m one of the people in the tiny, overlapping space. However, for anyone else in the vast minority, I came across a Tamagotchi Blackberry theme!

I personally find it a little hard to use because the icons don’t really indicate what the application is, but if that doesn’t matter to you, it’s adorable. The theme looked much better on my Curve 8330 than in the screenshots. You can download the theme free at the BlueRoomSolutions.com forums. You don’t have to register and you can download the theme in your BB browser directly.
