Does the Samsung Impact T746 work with wind mobile?

If unlocked, could I bring the phone & use it with their company? They only have 4 phones to choose from & I don't like any of them.

This is the frequency the Samsung Impact supports:

2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 1700 / 2100
