Why SHOULDN'T I upgrade to 8.1 on my AT&T Lumia 920?

[decheung]

Hey folks,

I'm super excited about 8.1. Finally! Action center!

That said, I see that upgrading to 8.1 preview wwill nuke all the carrier "optimizations" on my AT&T Nokia Lumia 920.

Is there anything I will lose out on by upgrading? What are the downsides to doing this?

​Thanks!
