I updated my Pebble iOS app and watch yesterday as soon as the App Store became available.  I have to say they've done a fine job of bringing all the apps and watch faces together into a nice, easy to use service.  Being able to touch two buttons and load the app or watch face onto the Pebble is very easy and beautifully integrated.  My LCARS watch face wasn't compatible with v2.0 unfortunately, so I've started using SmartStatus instead.  Not strictly a watch face, but an app that includes the watch face, plus battery status icons for both the iPhone and Pebble, next calendar appointment, and the current weather.  I like it!

Anyone else updated and have any app or watch face suggestions?  Post them here!
