    When upgrading to the 4.5 os for the curve is it necessary to delete the 4.2 os first?

    I'm not experienced to know if it would be beneficial or not, but I DID NOT remove 4.3 before updating to 4.5.

    you can, but not required. If you do a search for "proper upgrade/downgrade procedure" you'll find all the instructions you need. It states wiping the phone (i.e. removing the old OS) is recommended but not required.

    That being said, I've upgraded my Pearl numerous times (I'm up to 4.5.0.89 as of this afternoon), using other carriers' versions, without wiping. I've been using CrackMem and it runs swimmingly.

    +1. You don't HAVE to wipe or delete the old OS. When you do an upgrade with DM, it will essentially wipe it for you. However, I personally like to wipe it AFTER doing a backup because I want to make sure that there are no issues with the installation of the new or beta OS.

    Just one more point. I usually recommend leaving the old OS in
    place in case you need to rollback from the OS that you installed.

    Just saves you the trouble of reinstalling it or in some cases trying
    to find it.
