I got a text over the weekend from T-Mobile notifying me of various trivial stuff about my account, but it also said there was an update available for my phone. I went into Settings > About and tried to update both System and HTC but neither had anything available.

Did anyone else get this notification?
Is there a new update available?

I kinda suspect this was an old notification in regards to last year's minor OTA update. But I was hoping it was a surprise ICS update! Bah.
