    So what was the point of the swap partition on my SD card and Apps2SD?

    I followed the steps on BlackDroids forums for partitioning and ect, flashed to UD 10 and enabled the Apps2SD….but do not know why…lol.

    Can someone tell me in plain terms the benefit or reasoning of why they say we do this? Is it so we never have to install our apps again on a wipe or what? I apologize if this is covered somewhere else and I missed it.

    Exactly.

    I'd like a more in depth explanation of the whole swap file partition benefits and how it all ties in together though.

    This is mainly for people like me.. who install 150+apps, and use up all the internal memory, therefore making the phone run SLOOW..

    With apps2sd, your ability to install apps is only limited by the "ext" partition size, without slowing the phone down.

    Since apps are on your sd card, you can hop between different roms or different rom versions, doing a wipe data+cache, and all your apps will show up, as long as the rom supports apps2sd.

    The swap space is a bit less important - in case the phone needs a bit more memory it can use space on the SD card - it's a standard linux thing to have a swap partition on your HD if you run low on RAM, although these days machines have so much RAM that swap is becoming a bit anachronistic.

    I would not recommend using both apps2sd and swap as it can slow things down quite a bit as they both fight for I/O on your class 2 sdcard. apps2sd is handy for changing roms and is built into koush/cyanogen so it works on all of the roms based on it, which is many. As far as swap, unless there is a specific reason, I would not run it. There is one rom I am aware of that requires it, other than that it was really needed on the older phones, not so much on the droid. I see instructions telling people how to do it, but not why... they should be told... just because you can doesn't mean you should.

    Are you recommending uninstalling swap or just turn it off, I was not sure when I partitioned my card why it was need but followed the instructions hoping to use it and learn but did not! What exactly can you do with swap or what is it actually doing?

    Swap takes the cache and sends it to your sdcard. It's great for roms like the Zeus Droid desire. Because it allows the phone to keep enough RAM open so it doesn't close rosie. For other its not needed and unless the script is added to auto start swap or you do it. That partition is not used

    The potential for Apps2SD with a fast sd card is awesome, essentially you're looking at unlimited space for applications, while releasing space for more OS features. Also, as pointed out, switching roms, having your apps there and just restoring the data to them on the fly.

    It will be interesting to see as more roms adopt it.

    If you installed the DroidSwap application then open it and turn swap off. Then set it to not start on boot.

    If you want the space back... well you would have to back up the sdcard, sd-ext to your computer. Format the whole card again, then redo the partitions and copy everything back... probably not worth the hassle unless you made a large partition and need the spacce back.

    I followed those directions to a tee with swap, how do I go back and put the swap space in fat 32?
