I just got upgraded my D1 to a DX...and I thought it would feel Huge.. But it does not .. in Fact it is thinner and lighter than the D1 so I think the DX is smaller.
I was wrongly told by Customer Service that the X is upgradeable to LTE .
I may send it back.. but My other line will be due to Upgrade in April ? So I am not sure if I may just keep the X..?
