Well the whole "dropping it in the toilet" might have something to do with it. I'd just try to show your mom that you are more responsible, do your chores without being reminded, you know, that stuff. And offer to pay for at least part of your new cell phone.

Or it could just be your contract isn't up yet, ask your mom if your cell phone has a contract and how long it is.
