I've been using this for about a day now and have found two things that if updated would make it perfect.
1) Update the In call wallpaper. Either make it default or make it transparent (if possible). The image you chose makes it difficult to read the orange text.
2) It appears that there is a minor glitch when in call. The bottom "Carrier, battery, signal status" seems to show up then disappear or not show up at all at times.
3) I love the message indicator placement under the battery, however if you get 1 sms/mms and 1 email the email notification gets pushed over the clock.
Please don't let these suggestions come off the wrong way.
