If you own a jailbroken iPhone and are looking for a new app to test out, you might want to check out Infiniboard, which has just appeared on Cydia. This little app allows you to scroll through your iPhone app pages vertically, instead of the default and boring horizontal scroll. It certainly looks like a useful feature if you have a lot of apps, though we don’t expect to see something like this built into a future version of the iPhone OS. Would you want to be able to scroll vertically on your iPhone, or is horizontal good enough for you? Video of it in action after the jump.
