I have 4 gmail accounts on my iPhone- always worked fine so far. Since about Thursday my main (gmail) account exhibits some odd behavior. The most recent message doesn't appear on the iPhone (Mail). It may take up to 24 hours for the most recent message to finally appear in Mail. If a newer email gets into my gmail inbox, the previous message (that wasn't available on the iPhone) suddenly appears in Mail- but the most recent message doesn't. I've deleted/re-added the email account on my iphone, and disabled/reenabled IMAP in my Gmail account- to no avail. The other 3 gmail accounts work w/o any problems. Any help is greatly appreciated.
