can i use the HTC touch pro 2 as a GPS just like i do the one that sticks in my window?  if so, how?  i heard that there is a free application i can download through google but i dont know how to get started????

The free app that you are thinking of is Google Mobile Maps the US Cellular version of the Touch does not have built in GPS so you would need to get a BT GPS PUK to use with your device; not sure if GMM supports this configuration.
