Does anybody else have a 650 that rattles like crazy when shaken? I know it's more than likely the battery for some reason but I was wondering if this was common? Also, I have 2 mozo glam cases and noticed the phone rattles in both as if the cases are slightly larger. Is there a size difference between the cricket version and unlocked? I also had an unlocked version for a day that I returned because lack of LTE and that one fit snug and didn't shake in either mozo's. Thanks!
