Recently I've had massive problems with error -67 and all of my navigation programs crashing on startup. Driving me nuts. Finally called Sprint and got Tier 2 support. Got a cute sounding girl named Krystal. She said that living in Brooklyn I should have 4G service. Here's what she did:
Changed my NAI from one name to another (on her end)
had me take out my battery for 5 minutes then put it back in.

edit mode
put in password
click Data Profile
Menu then Restore
Don't touch the phone. It will reboot and then enter Hands Free Activation. Let it do it's thing.
After it's all done go to Settings
About Phone
System Updates
Update Profile.
After all this you may get Error -67 one more time.
After all that I noticed that suddenly I had full 4G service. This is in Red Hook, Brooklyn. It worked for me all the way up the BQE.
Amazing! I'm a happy camper. Check out the numbers.
Just wanted to add that I'm rooted using Unrevoked3 with SetCPU and ROM Manager.
