Anyway, the only thing I remember this happens is you did an OTA update for Samsung Captivate. That update is rather old (Sept. 2010) and you should be on latest Android 2.2 update anyway. That OTA update is flawed with problems (like large percentage of those did OTA ended up with a bricked phone). That's why the latest update is not OTA. See the sticky thread about how to get 2.2 update for your Captivate.
