Imessage won't work/activate after 5.1

I updated to 5.1 this morning, and now my imessage won't work. I try to turn it on, and I just get an activation error. "An error occurred during activation, try again".I've read in some other posts that my phone number should show by the imessage option? I don't see it anywhere. Once I get the activation error, then it provides me with the option to sign in using my appleID, but it when I do, it just keeps on reverting back to the sign in screen and won't connect. I've read through this forum and tried everything that I found - checked the date/time settings, checked my phone number, reset the networks, hard reset - and still it won't activate. What do I do?

iPhone 4S, iOS 5.1

I tried a bunch of stuff. I just restarted the phone (turn off and back on) and it's working again. Not sure how long it will last. I did recieve a spoof Apple email a week or so ago saying my account had been charged $4,000. I knew it was fake because I don't have a limit that high. I wonder if mine was messing up because they wanted me to verify I hadn't been compromised?

Mine didn't work for 2 months and this fixed it, so I posted it in another discussion and have been getting "thank you" replies nearly daily:


Just update your date/time settings:


Settings

> General

>> Date & Time

>>> Set Automatically: Slide "ON"...If it's already on, then slide it off, chill for a bit (maybe restart it), then slide it back on.



I am using an iPhone 4 with iOS 5.1, but other users with 3GS, 4S, and even iTouch devices replied that it worked.
