I am sure most of you must have seen the Ads of App store on television. App Store is a big success for Apple. You can get loads of free applications. Lot of applications which were available on Installer/Cydia earlier have decided to go legal. Most of them are not free anymore. The only application(that i know of) which is still free is Fring(application used to make VoIP calls to your Gmail,Skpe etc friends). But don’t worry there are are lot of free applications to try. If you haven’t installed any applications, give it a shot.
