I'm still running on v4.0421.4 and want to make sure that this is fixed before paying for the upgrade.
Sometimes after a while of usage (don't know what triggers it), the phone will stop notifying me of new sms messages. It will receive them, show the "1 New Message" and everything, but it won't make a sound or vibrate. If I power-cycle the phone, it starts working again.
Since I hardly ever turn off the phone, it is very annoying.
Can anyone confirm that this has been fixed?
