I got the OTA 2.1 on April 3. I turned on live wallpapers a couple days later. Sometime later (I can't remember if it was immediately or a couple of days later) I noticed that I was no longer getting regular email notifications in K9. It was more than just the phone not telling me a new email had shown up, it wasn't even downloading them. Emails would come in if I manually checked, but that was it. I turned off live wallpapers this morning to see if that was the problem, but so far, no change. Anyone else having problems with K9 since 2.1?
