Hi, I upgraded from an original Motorola droid to the droid 4 (the new slider one). My email will not stay synced. Is this a widespread issue? I have been waiting on a fix for a month or two and haven't seen any updates. It syncs roughly once per day and is causing me some problems because I am missing important emails... The email server that I am connecting to is a Zimbra server. I am using the regular email client that comes with the phone. I also have gmail accounts synced on the phone using the gmail app, but those are fine and update almost instantly. Thanks.
