I have not tried much. I was able to get data on Reliance 1x Network on Bionic. But it fails where these is EVDO coverage. Reason unknown.
APN / ppp-ril.options both do not work even if IP behaviour is set to Simple IP. There is a build.prop tweak to get it working, which I have not yet tried. Once we have APN / PPPD working in CDMA, data with OMH is possible. Since Razr, Bionic take everything from OMH, even the PPP HDR passwords.
I do not have any such handset like Razr, Bionic to try this out with, So I cant help.
