    Ok I would like to have multiple roms to switch between. The problem is that the ones that I like require partition the sdcard, and wipe. I want to know how to keep some ready for a fast change.
    I thought about keeping another sdcard on hand with another rom on it. would that even work? I have done a lot of reading, but it is one of those things that isn't described in detail.
    If I used another sdcard how big should it be? I have a 4g extra card, I don't save too much stuff on my phone. I back up photos on my computer, and run on the lean side. No excess apps. Just a few questions need some help to find answers.

    Now just to be clear, roms are not flashed to the sdcard, so just changing out an sd card will not result in the phone running a different rom. You still have to flash the alternate rom you want to run.

    A different sdcard will help if you would like to install apps to the sdcard (A2SD) but you are switching between roms that use different A2SD schemes (such as Froyo and non-Froyo roms). If you're not switching between roms that use different a2sd schemes, then you would want to use the same sdcard, otherwise you would have to re-install apps again.

    If you don't save a lot of stuff on the phone, then yes 4gb or even 2 should be plenty.

    Sorry I didn't explain myself better. I know that I still have to flash the rom to the phone. I can keep different zip files on different sdcards. If I nand back up one rom on my phone and switch the sdcard would I have to wipe to run the new rom. Cause if I wipe I lose the nand backup. Will all my apps be saved to the sdcard?
    Sorry that I am not good at organizing my questions.

    You do need to wipe when changing roms. However, nand backups are stored on the sdcard, a wipe won't touch your sdcard contents. Yes, nand backups get all your apps and data. Keep in mind though, a nand backup will not give you the ability to restore apps to a newly flashed ROM. A nand backup is only good for reverting back to the way the phone was at the time of the backup.

    If you are a frequent rom changer, then you might look into an app called TitaniumBackup, which can backup your apps and data. You can then re-install Titanium on the newly flashed rom, then restore your apps and data.

    You are the man. That answered my question better then what I have been able to find. You hit all the major points, even with my poor way of writing them.
