Most definitely when you send using Google's smtp server it gets put in your Gmail->Sent Mail folder.

Are you using Gmail's smtp server?

As for starred, they will be removed from you inbox view on the iPhone, but not Gmail. But if you get used to this on the iPhone you just go to the Gmail->Starred folder on you iPhone and you will see all your starred messages.

If it left them in the inbox there would be no way on the iPhone to distinguish Starred messages from other inbox messages.

1) good point – personal preference i suppose. when i delete something i don't want to ever see it again. if i wanted to archive it i would move it to all mail folder.

2) not true – at least on my iphone.

3) yes, but then they no longer show up in the inbox – which destroys the benefit for me at least.

(1) You should definitely not set your iPhone trash to the Gmail trash. Doing so will cause any mail deleted from the iPhone inbox to be deleted entirely from the Gmail account after 30 days, including being deleted from All Mail. This is not the desired behavior. Instead, the desired behavior is that deleting a message on the iPhone should only remove it from the Inbox, but should retain the message in All Mail. This is the equivalent of the Archive function on the Gmail web interface. The beauty of the Archive function is that it lets you get stuff out of your inbox, while retaining a copy in the All Mail location so that it is searchable later if you need it. I don't think people should set up their iPhone in a way that undermines the All Mail functionality, as that is pretty central to the Gmail experience. To do this, you just use the iPhone's local trash folder. This is explained on the Gmail help pages at https://mail.google.com/support/bin/answer.py?a... (click on “iPhone”).

(2) You don't need to set your iPhone sent items to the Gmail sent items. When you send something through imap.gmail.com, it automatically adds that message to the Gmail sent items. This is also stated at the link above.

(3) You can definitely flag messages from the iPhone. You just move the message from the Inbox to the Starred folder (to do so, just open the message on the iPhone and click on the Move icon, which looks like a folder with a downward-pointing arrow on it). Like you said, you can then view all flagged messages in that Starred folder.
