Sprint TP on Alltel

[rev800x]

I just bought a TP off ebay. I'm wanting to use it on Alltel. What changes are needed to get phone, data and MMS to work? I succesfully configured a Touch a while back to work on Alltel that was Sprint branded. Will I basically need to take the same steps or are these two phones totally different? I have not recieved the phone yet but want to get prepared and set up to configured it for Alltel. I already have the stock Alltel ROM for it.
