iPhone - very high data usage (email stuck in outbox)
A user managed to hit O2 1GB data usage limit on iPhone 5 in two days! He was normally using under 100MB per month and could swear that he hadn't done anything unusual in these 2 days.
After checking that backups and updates over cellular were disabled and there were no suspicious apps running, I added additional data package and reset iPhone data counter. In couple of hours I checked the iPhone again and to my surprise it had already uploaded over 40MB of data over cellular network.

iPhone stuck on Apple logo
iPhone stuck in an infinite reboot cycle: starts, gets to the screen with Apple logo and spinning circle, then after a few minutes reboots again.
Phone was fixed by putting it into a recovery mode and doing a restore via iTunes. Be aware that this resets the phone to factory defaults which deletes all apps and data from the iPhone. This also updates iOS to the latest version so if you had a jailbroken phone it will restored to factory iOS version.
Gmail email flagging gone in iOS 6
After upgrading iPhone 4S to iOS 6 noticed that there is no more Flag email option in Gmail account. The only option is Mark as Unread.
Gmail account was set up as Exchange rather than default IMAP account. After checking account settings I found that there is nothing in Domain field. Adding google as a domain initially seemed to have resolved the issue, as Flag option was back where it should be.
