Now this is little annoying if it's true. Looks like I have to delete my current version of the app from iPhone to get the newest available version otherwise the newest version does not install. Now whenever I see any new updates to any of my existing apps on my iPhone I immediately try to install them. Almost always, when the update tries to install itself, the message something like this comes "....Update will be available when the iPhone is connected to itunes" with Retry and some other option. Now when I try to update the Apps using itunes, I get some error message something like "The application could not be installed because an unknown error has occurred (0xE80000002E)." Now if I delete the old version from my iPhone and try again the new installation works fine. Now this is where I have problem. For example, my stock tracking app, if I delete it, I have again re-enter all my Watch list all over again. This is annoying. Please let me know if I am missing something or this is how apps updates install.
