AirDroid is a fast, free app that lets you wirelessly manage & control your Android device from a web browser Over-The-Air.
This is the best wifi phone management software that exists on the market. I'll definitely be using this application for quite some time to come - being able to use a keyboard to send texts to people is going to be nice. Best part is it's FREE.
