(it even works on 1x)
When I first got my phone activated at a Cricket store, I only had 1X. I remember youtube wouldn't load properly and it was very frustrating. Connected my phone to the PC and read the manual. I noticed the 3G symbol was missing so I called customer service and reactivated the phone. Youtube ran very smoothly after that.
