Just wondering, what are the limitations you have run upon so far? Previously what phone did you use?

Oddly, i tried accessing the Facebook App and the People hub this morning. But it says they can't pull data. Neither wifi nor Edge nor 3G. I wonder if it's a server issue or something.

Which beats ? Shouldnt be any problem as long its compatible.

Sadly no, the latest firmware for 900 doesn't address the camera problem, at least I see no improvement on the changelog.

yo! I see some of us are eagerly to get the update. No major update that increase the overall performance but instead:
Lumia 900 version 2175.2101.8779.12201: Enhanced sensitivity for proximity sensor performance and improvement to your phone’s screen colours in low light conditions.

And according to local Nokia site, still no news about the update but I see Camera Extras are available for Lumia 800 & 710. However you may try the NoDo update trick mentioned in other lumia thread by apecx92 if you're very desperate to get the update. Also camera extras will be made available during the mid or end July.
