    I was jailbroken with 2.2.1 and just recently updated to 3.0 and re-jailbroke. I've always shown the available memory in the status bar so I could monitor different apps' memory usage. I could usually tell when an app that doesn't manage memory very well was about to crash.

    Well, after updating to 3.0, and getting rid of all my jailbroken apps except SBSettings and Five Icon Dock, I have much more memory available. Before, I would consistently have between 14-18MB available when Safari was running in the background. Some apps would cause the available memory to go down to 6MB and that is when it is ready to crash. I now consistently have over 30MB of free memory when Safari has only one page loaded in memory.

    I guess a nice restore/update every once in a while can help recoupe some of the phone's performance.

    Either that or maybe 3.0 manages memory more efficiently.

    I'm suspecting both. I doubt I'll re-install all of the Cydia packages I had before, so hopefully I retain most of the available memory.

    I was messing with Safari to see how much memory I could use up and I got down to 9MB. It turns out all 8 pages will cache, so they don't have to reload when switching between them. 3.0 must have freed up some memory to allow this.
