I tried the Jellywiz build of it last night. It way pretty buggy (gallery didn't work, lockscreen was not ledgable) but these issues were with the ROM, not the base. Seems like the biggest adjustments were to the rpm/modem. I was getting a pretty good and steady 3G connection. That wasn't the case with the last modem (data drops, slow downs). I take it like this; J1 seems like a near complete public release, at least 95% stable if not highed. I Odin'd back to stock rooted and now idly await the official release. It's gotta be right around the corner. Releasing Jelly Bean around Christmas and advertising the crap out of it would more than likely elevate the hell out of Verizon's sales. I can smell the cheesy Christmas morning themed commercials now.
