3G problems with the HTC Nexus One, or is it a T-Mobile issue

There has been a slight drawback for some new Nexus One users.  If Google planned the release of their Nexus One phone to go smoothly, then they can forget about it because there is a slight hitch in the plan as some users are having problems with the 3G network.   Many are losing their 3G on the Nexus, and then getting bumped down to EDGE.  It is unknown why this is happening and it is also unknown who is to blame for this problem. 

An article on nexus404.com states that it lies with T-Mobile.  As the article states, one users contacted HTC about this issue and where directed to talk with T-Mobile.  Even though HTC seems to be laying the blame on T-Mobile, many users are not convinced as HTC and T-Mobile can't seem to give any help on the matter.  One user even got HTC to replace their handset because of the certain difficulties. It is commonly agreed that it must be the phone, hardware or software. 

Anyone out there having the same issue?
