I just got the Evo last week and since the first day I have been getting an error 67. I have been in contact several times with Sprint customer care (you can get more details in my post in this thread )and the last thing that I was told was. On a roaming tower, which I am on when I am at work, data is not guaranteed. Now I just have a few questions... Is it because of CDMA? I mean, do the GSM networks in my area have a conflict with sending data to a CDMA phone? Is it due to not having 3g coverage? I know with my past phones if a 3g connection was not available it would revert back to an EDGE connection. Can the EVO do that? Or is it because of some contract dispute that the roaming towers won't let the data traffic threw? Seeing how most of the time I will be in a roaming area I would like to know if there is a light at the end of this tunnel, or will I just not be able to depend on my data connection.
