Sad to say, I'm really not happy w/any of these new 1st series phones. It's about time they started making stronger phones but the new 8 core back's up my decision. I'm off contract now & I don't plan on going back on contract (rip-offs), so I'll use my D3 on Red & AT&T = no contract & choice & better como. SIM cards are the answer, if you have one you can make the decision. Just get it global & (legally) unlocked then your on your way. We'll see proof w/the next conference.
