Market Help

[Squee393]

Does anyone know how to change the settings for the Android Marketplace? I have the canadian version of the Samsung Captivate. I recently moved back to the states and would like to know if theres a way to change the location for the marketplace. I keep seeing the prices in canadian dollars. And I can't install some apps cause it thinks I'm still in Canada like Amazon mobile and the Nook App.

Also, anyone know a legit website to unlock a Captivate (I896)?

Thanks!
