Windows Live Mobile (beta) is now once again up and running, and it is awesome compared to the built-in MSN host. You can download the CAB file below (simply copy to your device or storage card, run, and you're good to go).
It is slow for the first few minutes running as it syncs all your contacts and such (it's not a bad idea to backup your MSN contacts from your PC first). Be patient, because after it's done the syncing, it runs fast and smooth (on my Axim X51v at least).
Enjoy! Oh ya, post your thoughts, opinions, tricks you noticed, etc.
