My fiance got this text today. He received the actual OTA for 2.2 over a week ago. And he's not rooted. So I think it is just going out to everyone.
I never got it, but I assume that he got it because he's the account holder, not me. It still amused me when he gets the text, reads it and just says "no sh!t Verizon, figured that out over a week ago!" LOL
