Hi. I just found out, to my dismay, that shifting a device from CDMA to GSM erases all voicemails. Had I known this would happen, I would have taken steps to record the information I had been storing in those voicemails. It might be a good thing to put a bold warning on the page that discusses shifting from one platform to another so that folks can save anything they want to keep. Thanks!
