Cant download a single app on market. Same problem every time. I click Install, accept the permissions, it says " Starting download", then "Downloading" and appears in the notification bar, then get stucked and says download unsuccessful. All this within 10 seconds after pressing "install". Clearing cache or uninstalling market updates doesnt help.
Close all your open application
Click on Application -> Settings -> Application -> Manage Applications
Click on menu and select Filter -> All
Now look for Checkin Service -> Clear data -> OK
Now look for Download Manager -> Clear data -> OK
Now look for Google Talk Service -> Clear data -> OK
Now look for Market -> Clear cache -> OK
close all apps and start market
download & enjoy.
