Anyway to make HTC Thunderbolt work better at my house (Wi-FI?)?

Please gary listen to me... put that phone in the box n send it or take it back and get your money back. You will have many problems with that phone. You obviously have not researched the phone with user reviews, you would see the mess your in. You cant make calls through wifi or text unless you have certain apps for that. Message me if you have concerns.
