I'm writing this mostly as a heads up for those who, like me, didn't know that if you clean out your gmail mailboxes you lose all your i-device notes that were associated with your gmail email address. I was on my macbook a while ago where its much easier to clean out gmail mailboxes than it is on iphone or ipad. And I went overboard emptying my boxes of years of messages. But then found out I had also deleted years worth of valuable notes. Thankfully I did not lose any contacts even though they too are associated with my gmail account. I don't get why the notes disappeared and the contacts did not. Anyway just wanted to put this out there so maybe someone else can avoid this horrendous mistake.
