Well, I think it depends on whether the question is easily solved or not. I genuinely believe that a search on google would've yielded some results relatively easily. Wasn't really trying to be an a-hole, hence the smiley afterwards!
And to answer your supposedly original question, yes there is a setting in the phone that will force 1X or EVDO. You just have to enable it first in the registry once, and after that you will be able to just change it in the phone->options->services->mode of operation page. You won't have to change the registry everytime..
In case you weren't able to find the instructions in the link

Change from 1 to 0
Save and soft reset
After resetting, go to:
Start > Settings > Phone > Services > Mode of operation
You will now have 3 choices, Hybrid (default), EVDO, and 1X. This is great for those stuck on the fringe areas of 1X and EVDO!
