You know how easy and natural it is to hang up a call on a cellphone by sliding it closed or flipping it shut? It's a small satisfaction that's been lost on touchscreen-only phones, but it would seem to still make sense on something like, say, the Palm Pre -- just not to Palm, it seems. Well, it looks like unofficial patch maker KeyToss has now finally stepped in and done what Palm hasn't, and produced a patch that does nothing more than let you end a call by closing the slider on your Pre. Who knows? You might even start hanging up on people just for the fun of it. Hit up the link below for all the necessary details on installing the patch.
