With three days left until the release date of T-Mobile's HD2, we want to show you the differences between the T-Mobile version and the international version of the HD2.
T-Mobile HD2: 122x67x11mm / 4.803×2.637×0.433in
HTC HD2: 120.5x67x11mm / 4.744×2.637×0.433in
The T-Mobile HD2 is 1.5mm / 0.059in taller than the International HD2, a difference which in my book is negligible and I'm sure you'll find it too, in case you happen to own an international HD2, so no need to be affraid, it won't stand out compared to it. Both devices weigh 157 grams (5.54 ounces) with the battery attached so there's no difference here.
While the International HD2 has white logos on the hardware keys, the T-Mobile HD2 has a green Call Start and a red Call End button. Additionally, at the top of the device, just below the speaker, you will find the T-Mobile logo branding right above the screen.
T-Mobile HD2: 576MB RAM, 1GB ROM
HTC HD2: 448MB RAM, 512MB ROM
The T-Mobile HD2 has a 128MB RAM advantage over the HTC HD2 if we are talking about the stock specs. Latest developments demonstrated that the International HD2 has the same amount of physical RAM, but the additional 128MB has been hidden and thus unavailable, but unlocked via applying custom ROMs.
As far as ROM is concerned, the T-Mobile HD2 has twice as much storage memory than the international HD2, mainly because of the customizations the operator version has (not to mention the Entertainment package including Barnes & Noble eReader, Blockbuster on Demand — Blockbuster's first-ever video download application on a smartphone, MobiTV, Gogo Inflight Internet Services — six month trial for inflight wifi services on over 2,500 daily U.S. flights and Slacker Radio).
Still talking about memory, the T-Mobile HD2 comes with a 16GB microSD card (featuring copies of the Transformers and Transformers 2 movies) while the HTC HD2 came with a 2GB microSD card or none (depending on where you bought it).
T-Mobile HD2: WCDMA/HSPA:
1700 MHz (AWS) / 2100 MHz, GSM: 850/900/1800/1900 MHz.
HTC HD2: Europe: HSPA/WCDMA: 900/2100 MHz, GSM: 850/900/1800/1900 MHz. Asia Pacific: HSPA/WCDMA: 900/2100 MHz, GSM: 850/900/1800/1900 MHz.
Main difference here is the one and only vital one: the T-Mobile HD2 supports the 1700 MHz band not supported by the International HD2. Additionally, we've posted about how to get AT&T 3G speeds with imported Telstra HD2 from Australia, which supports UMTS 850Mhz.
The International HD2 came with a leather slide-in/slide-out pouch which offers full protection to the screen and overall to the device, but there's no way of telling if you have a notification since the pouch covers both the screen and the upper part where the LED is. Compared to this, the T-Mobile HD2 comes with a gel-case which offers protection only to the back part of the device (it's cut-out for the camera and speaker) but no protection at all for the screen (which is glass and nearly impossible to scratch but it brakes), thus making it easy to notice your notifications.
As far as HTC Sense is concerned, the T-Mobile HD2 comes with a version of Sense that has two additional tabs, at least according to leaked ROMs: the Document tab and the eReader tab.
