I'm having problems with the app store, and it seems to be a little different to the ones already listed here. I'm hoping it's a problem with the Android app store or something... Anyway, I'm just getting "download unsuccessful" every time I try to get an app. The main bit of advice is to clear the caches, or delete the data, from a few things. I've done this, except for "Google Apps", because the delete data button isn't there. I've also had it suggested that it's changing from one sort of google account to another. I've had gmail for years and years (since the early days of its beta) and have never changed it, or any settings related to it. Sites have suggested logging into and out of Google Talk, which I've done. None of these solutions have worked. But if you know a way to make the Google Apps "delete data" button magically appear, or some other way round my problem, or just the comforting knowledge you're all having the same problem, please help. After my awful experience with a Desire, I'm beginning to get a little disheartened with Android.
