So I went back to the Bell PRI and then repeated these steps but was unable to get the Sprint PPST to do the same thing. So I'm back to the test PRI 2.03_003.
No idea what happened the first time I used the Sprint PRI on the v3.02 image but it probably didn't finish correctly.
When I had PRI 2.04 installed with the 3.02 PPCKitchen ROM I didn't have access to the internet... phone calls still ok.
I wouldn't try any of this unless you are feeling lucky.
