Hi, hoping someone can explain the various radio options to me. I downloaded the app "network" from market, now I would like to restrict my phone, but I don't know which category suits or meets what I am expecting the result to be. Sprint voice and 3g. My options are: WCDMA Preferred GSM Only WCDMA Only GSM Auto (PRL) CDMA Auto (PRL) CDMA Only EvDo Only GSM/CDMA Auto (PRL) Unknown THe only thing I am really wondering is should I use cdma only or cdma auto (PRL)? And what the heck is WCDMA??????
