With v2.1, Exchange email was more than perfect. In that, often I would get a ping on the iPhone to advise of email before my Outlook client on the PC. Now, with v2.2, it is often the case that I have to start the email app, before email is received. Is it just me? Nothing seems to sort the problem, have re-started, turned plane mode on and off, gone into mail app and then held down hme button until app quits. in v2.0, holding the home button button whilst in mail app, nearly always sorted the problem, not now.
