OK iFans, I've had my iPhone for 2 days and completely filled it with apps. I discovered Cydia, read all the stuff so I thought i'd try it out, downloaded it and nothing happened, it crashed and defaults to the homescreen. So I searched and searched to find a simple answer to uninstall it with windows. Failed. I stumbled across iPhone PC Suite and found out that it gives you access to the iPhones file system. through that you can add custom ringtones (of any length) and also remove apps.
