While i was playing around creating a mobile youtube app i got the idea to create stand-alone mobile social media apps as well. I know a person could do this with Fluid, but these are quite a bit smaller and require no work on the users part. These are just webkit wrappers that display the mobile version of both sites and are sized accordingly to look how they would on a phone. Once the apps are open if for any reason you need to go back or forward a page just right click on any whitespace and a dialog box pops up with forward/back/reload/stop options. Cheers.
