anyone else had problems using iMessage on beta 4?
finally installed it on my 4S to test some apps, and noticed that it's not detecting that contacts are iMessage users (ie green button not changing to blue), also if someone sends me an iMessage to my email address, it is not getting delivered to phone (only gets delivered to OSX).
my email address is along with my mobile number in the iMessage settings. i've tried turning iMessage off and back on again, also rebooted - all no luck.
