Review: Samsung Captivate
The Captivate supports most forms of messaging you expect to find on a device such as this. There is the native Android Gmail app, of course, and thankfully Samsung hasn't done anything to alter or improve it.
There is also a separate email account for POP3/IMAP4. I couldn't get it to work at all. I tried a handful of POP3 accounts, and none of them were ever able to authenticate. I have followed up with Samsung about this issue and am still awaiting a response.
SMS/MMS is supported in the "Messaging" application. This app works well. It offers threaded conversations, and if your SMS conversations are with Facebook friend, you automatically see their profile picture next to each message. (Also true if you've set up a picture ID.)
The Captivate also has instant messaging on board. Google Talk is a separate application and is the native Android app. Samsung hasn't modded it. If you want to use AIM, Windows Live, or Yahoo IM, you have to use the AT&T-branded messaging application. It works the same as it does on AT&T feature phones. I have no complaints with this app, but it could use a refresh. It hasn't been changed in what feels like years.
