When manually moving over ~2000 sent messages from the Sent folder in Gmail to the Sent folder in iCloud (through Mail.app), I noticed that when looking at the Sent folder in the iCloud account on my iPhone, the mail that shows is not the "most recent" 50/100/whatever. Instead, what happens is that a few recently sent messages will appear as expected, but then there will be a randomly-timed gap -- months, a year, something -- and I'll have a message sent in December of 2011 or so appear right next to one sent a couple of days ago, as if nothing was sent in the meantime. Sent mail viewed under other, non-iCloud accounts do not have this problem. The sent messages viewed under "Sent" in Gmail on the iPhone appear as expected, and if moved back to Gmail from iCloud, they again appear as expected. Suggestions appreciated.
