AT&T's SGH-i907 Epix Windows Mobile smartphone gets reviewed

While the i907 Epix's name might suggest that this smartphone has more to do with the i907 Omnia that Samsung sells in other markets, the Epix is really just a slightly reworked version of the company's existing i780 that is sold in Europe and Asia. As such, the vast majority of our original i780 review will apply directly to the i907 Epix, and we recommend you read that review once you've taken a few moments to look over what has changed for this AT&T version of the device.

Let's start off with the physical design differences. This are quite minor. The only obvious change that we can see in the i907 Epix version of the device is that it is thicker, which allows the Epix to hold a larger battery. This, of course, also increases its weight. The i907 Epix measures up at 116.5mm x 61.5mm x 15.5mm (4.6" x 2.4" x .6") in size and weighs a solid 136g (4.8oz). That's 2.5mm thicker and 16g heavier. It is still very pocketable, and the 7 hours of talk time or 14 days of standby time are well worth it.

In terms of hardware, there are other changes that are not so obvious from the outside. For starters, the i907 Epix has not only quad-band GSM/EDGE capability, but features 3G HSDPA support for the 850 and 1900MHz UMTS bands in the U.S. as well as the i780's 2100MHz band for Europe and elsewhere in the world. The i907 Epix is powered by a newer version of Microsoft's Windows Mobile Professional OS that the one used by the i780. The new v6.1 version supports threaded SMS and a few other tweaks.

Because of the AT&T branding on the Epix, there is plenty of AT&T specific software to be found on the device that was not available on the i780. AT&T Navigator, which makes use of the built-in GPS module, is a good example. Users will also find access to the AT&T Mall, AT&T Music, the Video Share service, and a nice IM client that supports AIM, MSN, and Yahoo! messengers.
