I tried it on my 8525 because I'm tired of having MMS issues, but I still had them after. However I still had spl 2.10 after installing it. It updates the radio though.
I'm in the process of going back to the HTC WM6 as we speak. and back to radio 1.47.
If anyone has a good way to get my MMS working properly let me know.
