I've been having this problem for some time now where my iPhone Gmail and MacBooks Gmail don't sync up. I typically have to go to Gmail.com to properly find Deleted/Sent messages. I want all 3 (iPhone, Mac, online Gmail) to all be 100% synced so if I deleted something from one, I can still find it on the other two. Right now if I delete something on my iPhone it's gone forever. I have to FWD stuff to another email if it's important enough or if I want to print it.
Any help?
