Hello, Hoping someone can help me. My HTC Desire won't let me install the Yahoo Mail app - it says on Android Market that it is already installed, when it REALLY isn't - I've never had Yahoo Mail before. I really want this app, as setting up Yahoo Mail through the normal mail app gives me all the spam (I've tried various things but nothing gets rid of it) and also it doesn't give me LED notifications when I have mail. Can anyone advise me on what to do to get Yahoo Mail. I really want to avoid resetting to factory settings, as this will remove all my installed apps. Thanks loads in advance!
