    I am using this for last two weeks. I am really enjoying 1% battery mode. 🙂 Very nice UI. I am satisfied with this ROM. Few things that bugging me are,
    * Swype keyboard is not there.
    * Launcher issues. I observed many times Apps/call-log/messages don’t open but home screen comes with out launching them.
    * Crash on Audio/Video chat on Gtalk. (in Skype its fine).
    * The laucher has provided with “Lock” mechanism through which we can lock apps. But Messages cant be completly locked in this way. Clicking on the delivery report notification or “unlock into messages” wont prompt for password.

    I got few more things but I hate essays. 😉

    Can I keep all my apps, or do I have to load them all from scratch?
    Does this firmware have the swype keyboard, and text-to-speech capability? These are 2 of the features I value most on my un-rooted SGS.
    If I install it and want to uninstall it, can I get back to my current configuration, or will it be as it was out-of-the-box, without any of my customisations?

    Same problem here, seems to remove all your APN settings and even when trying to request available network the crash comes in.

    Looks to be a basic theme over standard gingerbread, no real perks like overclocking your processor, or any other cool mods. Looks nice though but thats about it sadly.
