It's been nearly a year since T-Mobile released the Samsung Galaxy S in the United States, and this time they're back with the Samsung Galaxy S 4G.

The Samsung Galaxy S 4G is the newest revision (at least available to the public) to the Samsung Galaxy S (Samsung Vibrant).

Tech Specs:

• 1 GHz Processor
• 480 x 800 Super AMOLED display
• 5.0 MP Rear-facing camera and a VGA Front-facing camera
• 1 GB onboard memory, with up to 32 GB microSD storage
• 512 MB DRAM

The Samsung Galaxy S 4G's graphite-looking back complements the phone's sleek contour.

The first bummer: what we have here is a fairly noticeable gap between the glass front panel and the outer framework. It'd be less of a concern if a cell phone's primary home isn't the pocket of its user.

Gone are the days of mini-USB. The Galaxy S 4G boasts a micro-USB connector and a 3.5 mm headphone jack alongside the top of the phone.

A cool sliding door keeps the micro-USB port lint-free.

Well lookie lookie...what have we here? The rear panel is easily removed, revealing both SIM and microSD card slots, as well as what seems to be a replaceable battery!

As predicted (not that we're psychic or anything) the battery is easily removable, thus easily replaceable. Thanks, Samsung!

You may be asking yourself what powers this device?

• The 3.7V Li-Ion battery inside the Galaxy S 4G lists a capacity of 6.11 Watt-hours, or 1650 mAh.

Removing the microSD card requires little effort at all.

Let's remove those pesky screws.

• Samsung chose friendly #00 Phillips screws to hold the plastic framework to the Galaxy S 4G. Interestingly, these are the only screws in the entire device.

With the assistance of our good friend, the plastic opening tool, we can unclip the plastic outer framework of the Galaxy S 4G.

Adios plastic framework...we hardly knew ye...

With the plastic framework gone, we get a good look at the Galaxy S 4G's internals. The motherboard is quite compact.

The first item that is readily removable is the loudspeaker. Removing it requires a simple flip of the ZIF ribbon cable lock on the motherboard.

Camera assembly...be gone!

The compact front and rear facing camera assembly has a NEC MC10170 Image Processor cleverly attached right to its ribbon cable.

The rear camera can shoot stills at 5 MP and video at 720p. As in most smart phones, the front camera is VGA quality.

After removing a few more connectors, the motherboard assembly can be lifted right off the inner framework.

An interconnect board is adhered to the rear EMI shield and hosts the SIM card and microSD card slots. We popped them off as one piece to get a look at the ICs that make this thing tick.
