Just got off tech support at Apple and they said this seems to be a major issue. Not sure if they are working actively to fix it right now however said he would forward this to engineers for review. He recommended that more people call in about this the better and that would help engineers move to update the 4s code. He agreed that this seems to be a code issue. He said that also to try to reset the network settings of the 4s under Settings/General/Reset. And see if maybe this might help. I'll try this again when I get home. He did ask me how long it took before the 4s failed to reconnect to the MC. Told him I let the phone go to sleep when I went to bed and when it got up and woke the phone, it wasn't connected to the MC.

So lets get all you 4s and MC users to call in and complain. Let us know what they said to you and get a case number. I did. Hope we can motivate them to fix this. I would be nice to the 4s to auto connect to the MC with out any interaction. )

Keep us posted.
