I would assume the GSM overlay would be done much the same way the initial CDMA overlay was done in the US. When CDMa was first introduced, they took out 4 analog channles and made that part of the spectrum (1.25 MHZ wide) allocated to CDMA. The 4 analog calls deleted were replaced with 30 or so CDMA calls. Once they had more handsts out there, they then replaced another 4 analog channels with 30 more CDMa channels, until today they have like 1200 CDMA channels and 8-12 analog channels.

In GSM, you can block it out exactly the same way. Take out 6-12 GSM channels and replace it with 60 or so CDMA1x channels. Then as your handset mix changes, replace GSM channels with CDMA channels.

Also in analog, the highest 5% users were sent for free a CDMA handset. I would suspect they would have simliar plans. The announcement of the MSM6500 is exactly for supporting the GSM1x system and GSM fallback modes.

A short answer, yes they can share bands.
