Upgrading to Sprint's official WM 6.1 Rom

[ljstevens]

Hi
So I have a question. I put a Rev A GPS enabled ROM on my Touch. I had to upgrade the radio and the Coke unlocker to 2.31 (I think this is the version).

Now my plan is to install the stock new Sprint ROM, along with my own software and the TouchFLo/Manilla 2D theme. I would just like a clean Rom that runs fast.

My question is do I need to change or downgrade the radio and the coke unlocker in order to install this new Sprint ROM?

I would appreciate someone's advise, so I don't wind up bricking my phone

Thanks
Lawrence
