Just got my Milestone yesterday and I love it. However, I can't use 3G while I'm talking on the phone. My brother has the Milestone on T-Mobile and he can use 3G while chatting. Is this a network problem or is there a phone setting I can adjust? FWIW I can use 3G while on a call with my Treo Pro so I'm almost certain it's not a network issue. Thanks! I owned a Treo 650 and a Treo Pro before this, and I am pleasantly surprised by how easily it is to type on the soft keyboards especially in landscape mode. I am also seriously addicted to Robo Defense.
