natureboy88, glad my post helped you get your internet working...
I'm also in Denver, and so far have not come across any evdo cricket phones, flashed or otherwise. I've tried a bunch of stuff to see if I could coax a different prl OTA, but I always get 1040. It doesn't matter what type of phone I have, or what type of phone is listed on my cricket account.
To edit your data username/password, use the dial code: ##DATA (##3282), which works on all sprint phones, and some verizon treos too.
I'm not sure exactly which username/password this modifies, but I'm fairly certain it's the NAI username/password, which is generally part of a mobile ip profile, but I'm not 100% sure on that.
