I am running the official AT&T Froyo 2.2.2 on my streak. For the past couple of days I get a "Unable to install, please try later" message every time I try to download and install any app from the market. Before this I have downloaded many apps from the market with no problems. Also I am still able to download apps from Amazon app store. I tried clearing the Market cache and Market data but it didn't fix it. I also deleted all apps that I downloaded recently. Still no fix. Does anyone have any ideas, as this is very frustrating? Thanks for any advise.
