Okay so I updated to 2.2 and basically have been fortunate to not have many of the issues I see other users have been experiencing.....except-- I purchased "Ring Manager Pro" an application that allows me to create a list from my contacts and when the ringer is on silent their calls will ring, this function is imperative to me since I am on call at night and need to be able to receive calls from certain people but do not want to hear emails, texts, and calls from people that are just plain rude and will call at all hours. Now what happens is at approx midnight the ringer restores to normal now this occurs under any mode. I can go in and turn off all sound still at midnight sound is restored. Please help. Thank you for any assistance.
