Is there an HTC TP WiFi App that....

[md80boy]

I will use my TP (6850) as a phone and text, however I realize that the phone itself has wifi ability.
I do NOT have a data plan with Sprint - just phone.
I have a wifi network in my house. I was wondering if I could surf the web through my wifi network using only my network and NOT Sprint?
I am hoping there is a way to separate the two: phone via Sprint that I pay for, Internet through any open WiFi network.

Is there a way or App that does this?

Hey, in fact, could I Skype through it?

Any help for this noob would be appreciated!
