ATT doesnt OTA update the captivates... they use samsung keis windows program. and it sucks balls. once you flash custom... it only sometimes works.
thats why we use the Odin One click packages to flash stock roms (or other packages) to update the phones. Captivate > Development > Stickie > Odin One Click Master Collection (ATT). stock rom flashes that can be done at any time with any windows PC. you can even choose versions that are pre-rooted and have CWM installed!!
NOTE: stock sucks too!.. of course try it out.. see what gingerbread is... then get ready to get bored and jealous of everyone else and their fancy features...
CWM lets you flash things on the phone from the phone.
Odin lets you flash different packages (of same stuff) from PC.there are 2 odins. odin One-Clicks.. pre-packaged. one button.. click it.
and odin flasher.. you can choose what and where to flash files on the phone from pc
with a couple extra button presses at boot, you can boot into the CWM flasher to install full roms/ mods/ kernels or modems before android boots!~
On samsung galaxy phones we are usually able to build CWM into the kernel. (Captivate always) so IGNORE anything you read about using Rom Manager to get CWM *outdated/not needed for us*
