Software update on the Settings Menu

You can try, but if it fails I would not try again, because if you do, then the update is going to be re-downloaded all over again.

From what I have seen, most people have had it to download the update and then fail when it tries to apply it.  The end result is no update and your phone just chewed through however much data the download was because the Over The Air (OTA) update is downloaded over your celluar network and not wifi.

Many people applied the update through Kies Mini, but now Kies Mini is not working for a lot of people either, so something is going to have to be fixed before the Froyo update gets pushed out.

tell me this, go into your settings and down to phone info. What does your firmware say you are running? Does it have the words updated in it? If so then you are already updated if no then yes do the update.

Yes some people have experienced a problem with the update but once you do the update you shouldnt get another update for your phone so im betting that you are running a Captivate without an updated firmware

ya that is what most people said about the update

there is a few suggestions found here but people have mixed results and some of them require just a little knowledge but if you are willing to do A LOT of reading and are somewhat adventurous then you should be fine on most stuff
