I've had my Touch (Vogue) for a bit over a week and the EVDO has never worked. I finally called into Sprint CS after reading this thread and dealt with their Tech guys. After 1.5 hours and 4 techs, a supervisor from Tier III tech support (their highest, that I am aware of) informed me that my phone is defective, they cannot fix it, and I should take it to a Sprint store for a immediate replacement. We tried several tweaks in the ##DATA# menu, reprovisioning, soft and hard resets, and they attempted several things on the network side to get it to take. No dice. So I guess I will go grab a new Touch tomorrow. Good thing I haven't spent a ton of time customizing stuff...
Anyhow, just thought you all might like to know.
