Long story short, after rooting my phone and customizing it exactly the way i wanted it, i decided to see if I could get Mimocan's lag-fix to work on the Captivate. For those that don't know, this speeds up I/O by placing the some of the inner workings of the phone onto a EXT3 (or 4) partition on the SD Card. Some users have seen benchmark scores double using this method on other versions of the Galaxy S. I was too anxious though and didn't read through all the forums, as seems like Captivate owners trying this method have bricked their phones. For me, I was stuck so that no matter what happened when I booted up I went into recovery mode, however from recovery mode i couldn't select any of the options. I finally found this thread that has a one-click program to revert the phone back to it's stock state. I lost my apps, contacts, etc. But my phone was back up and running.
