Overall, is it safe to upgrade "leaked but not truly Official" ROM?

[superflysocal]

EDIT: i JUST REALIZED THIS IS NOT THE OFFICIAL ROM. WE CAN KEEP THIS GOING BUT I AM NOT GOING TO CONTRIBUTE TO THE CONFUSION BY CALLING IT OFFICIAL.

I have been debating back and forth between upgrading to the new rom or not.

When I had the mogul, i rmember when the first major rom update came out, i held off from upgrading and glad i did, because it had many bugs, and didn't add much. When they released the second major update, they had work the kinks out and added gps/rev.A.

Well now I'm in a similar dilemma, except this 1st major update does have GPS and rev.A which I have been waiting for. But of course there are many bugs reported as well.

My first question is, are there any bugs that are considered definite and real...meaning it has been confirmed by EVERYBODY who have updated to the LEAKED ROM? If so, what are they? (If you tell me and i collect hem and post it back on the first post here so that it is easy to find).

I know ther are other bug threads, but I am trying to focus on "confirmed" bug. If there are enough of these there is a good chance Sprint will release another rom soon. If most of the bugs are only in certain cases or situations, then they may not decide to fix the ROM.

Second, if you had to do it again, do you feel it is safe to upgrade? May be I should poll this.

2. Alphabet strip on the right side of Contacts program sometimes doesn't show up.
3. Vibrate mode doesn't stop vibrating until soft reset (UNCONFIRMED, may be a software conflict...need more of your input/comments)
4.
