I had this same problem with the first update, to which I got a new phone. I just updated the new phone with the new Gingerbread update and the POP3 email I have for my business is set to refresh / update every 5 minutes and it is not doing this. It's a work email so it is very important when I am not in the office.
Other then 'workarounds' any ideas to fix this?
Thanks in advance.
