    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.

    I'll let someone who knows what they're talking about explain this, but the short answer is "no." Also, the Eris is CDMA not GSM. That would be the original version of the Hero (the European one)

    Hm, I could have sworn their was a GSM Equivalent of the Hero, but either way, oh well. :(

    I know it prolly has something to do with the hardware/chipset, but was just wonderingg if that menu you can use to change the cell towers would be of use.

    I think you're correct--the radio on the US versions (Hero and Eris) is simply not compatible with GSM. If it were, you could probably use the menu you are referring to to switch frequencies.

    And like I said, the European Hero uses GSM, but the US versions do not. Its too bad adding radio frequency compatibility is so expensive =/

    Sprint Hero and Eris are CDMA. They do not support GSM radio signals. There is a GSM Hero, but flashing anything from it is a quick way to totally brick your phone.

    only Western Europe is exclusively GSM. SE Asia has an equal number of GSM and CDMA carriers. A lot of military members make a second living exporting certain CDMA cell phones from S. Korea because they will work on the Verizon network, not sure about Sprint. I am new to Sprint so I am not sure about their freqs. I also know some of the S. American countries use CDMA, as my phone worked in Peru, Ecuador and Mexico.

    There is more info here

    No. Two completely different technologies... two different radios, really.
