I know of at least ONE app that isn't showing up in the market. Its CLapp that just so happens to be my favorite Craigslist app. That's just one that I know of, I'm sure there are others. That may just be a Gingerbread issue and not a specific issue of this build. The online market doesn't have my phone listed anymore, just says"Verizon" phone. As such, it seems I've lost the ability to push apps to my phone from the online market.
Biggest omission I've noticed thus far is that my LEDs aren't functioning. That's a big blower for me. I'm anxiously awaiting to get those back.
oh, and I never did use the stock Moto widgets much, so I may be mistaken, but I THINK the weather app has been updated. Looks really nice. Uses the same scrolling effect that Moto employs for the landscape picture or music album view.
