Split your cash/phone up in your front jeans pockets and keep your eyes open, Rome wasn't too bad in comparison to Prague/Barcelona. Main thing is to keep tight hold of bags/pockets on the subway..
Edit: Don't carry all your cash around with you as well, keep some in the hotel. I think if the situation is right, anyone, no matter how much you think you're aware and ready and can get done.
