Ever since I got the iPhone 4 whenever I receive an email I get an initial vibrate as it shows up in my Gmail Inbox and then shortly after receive a second vibrate when it goes into my All Inbox. I know for some this might be a good thing but it is a bit annoying after a while. I tried doing a restore but it still happens and doesn't seem to be happening on anyone elses iPhone 4 that I know. Anyone experience this problem and find a solution?
