Myles Garrett came to the rescue at an Apple store in Ohio this week ... busting out his wallet to help out a guy who couldn't afford an iPhone -- and it almost brought a grown man to tears.
The Browns superstar happened to be shopping at the Summit Mall in Fairlawn, Ohio on Wednesday ... where 27-year-old JJ Remmy was trying to replace a cell phone that crapped out on him.
The problem for Remmy ... he was told it would cost $116 bucks to replace the device -- and he simply doesn't have that kind of cash.
