I know this is a rather odd question, but, I know that on the damageless rom, it defaults to locate for GSM Radio Towers. Now, I know there is two HTC Hero devices, The Eris (GSM Version) and the Hero (CDMA Version), however the ability to search for different towers in the Damageless rom has me intrigued on if it is possible at all. Why I ask is, I am going out of the country, specifically to the carribean islands and mexico. I am wondering if it is at all possible to use it like that. I really doubt it because I don't think that the CDMA version is backwards compatible with the GSM version, but I thought I might as well ask.
