Trouble finding a certain app in the app store? Well, there is a new website out there called iPhonexe (mobile version can be found here) that gives everyone with a iPhone a alternative to using Apple's official app store. While I personally have not checked for every single app currently in the app store, iPhonexe claims to include them all, broken down into categories ready for nice and easy browsing. Keep in mind that this does not bypass Apple's app store completely. If you click "Buy Now" you are taken directly to the app in the app store to purchase it via iTunes.
But wait! I've saved the best feature (by far) for last: the ability to search Jailbroken apps! I know there are other sites out there that you can use to see what is available on that side of the iPhone world but none do it this nicely. It is worth a look for sure.
