HTC's HD2 might have only been out for less than two weeks, but they still can't keep the phone in stock, selling out again this week. Furthermore, up to 21,000 HD2 phones have sold in a single day.
T-Mobile doesn't know when they'll get more HD2's in stock (and be able to keep them in stock), but they'll let customers know when more phones are available. For now, you can load Windows 7 on an iPad and pretend it's a giant HD2. (KIDDING!) [Slashphone via Electronista]
