Has anyone else experienced this problem? When I initially synch my iPhone 3.1 3GS it will show that I have 3.64 GB of Applications installed even though in reality I only have about 1.8GB of Apps installed. If I add or remove an application then iTunes will show the correct size of installed apps, until the next time I resynch with iTunes or restart my phone. What is up with this? I recently upgraded my Navigon version to 1.2 and I'm suspicious that somehow it is installed twice or the iPhone thinks it is installed twice. I would prefer not to have to uninstall the application from my phone and lose all of my settings as I have programmed tons of stuff into Navigon. Is this some kind of known bug? Any other way to troubleshoot it? Thanks.
