Hello, All of a sudden three days ago, having done nothing out of the ordinary, several apps ceased to be recognised on my screen (the icons went to generic android icons and clicking on them told me that the apps were not installed). So I went to the market app to re-install them to find that the market app itself doesn't work any longer. It starts loading, the screen goes blank for a second or two and then I'm back to the home screen. Before I do a factory reset, can anybody suggest an alternative fix to this problem? I'm running a stock T-Mobile G1, not rooted, not anything! Never had a problem with it. Thanks!
