Cingular's 8125 Pocket PC phone, the GSM answer to the 6700, combines a large comfortable keyboard and a full suite of communication options.

The Cingular 8125 is a rebranded version of the HTC Wizard Pocket PC phone. The Wizard is also sold in a slightly different casing by T-Mobile, under the name MDA (or MDA Vario, if you happen to be in Europe) and various other brands. Most of this review also applies to the Cingular 8100, which is a version of the Wizard without an embedded camera.

The 8125 bears a great deal of external resemblance to its CDMA sibling, the HTC Apache. Like the Apache (which is sold by Sprint and Verizon under the PPC6700/XV6700 name), the 8125 has a side-sliding keyboard, thick candybar design, and 2.8 inch QVGA screen.

Unlike the Apache, the 8125 doesn't have 3G data service. Users who want UMTS or HSDPA service on their handheld will have to wait for the HTC Hermes, expected out some time late this year. The 8125, meanwhile, hops along on 2.5G EDGE, which we'll talk about under Communication.

The 8125 shows a very squared-off profile, with a bit of rounding towards the back of the case as its only concession to ergonomics. Even so, it's reasonably comfortable to hold. The SIM card is housed under the battery, like most of HTC's recent devices. Unlike their Windows Smartphones, though, the miniSD slot is available externally, so you can get to it without much fuss.

A key flaw of the Wizard's design is the button configuration. The bottom front panel only contains four buttons: two softkeys and two phone keys. Absent are two buttons you need for proper one-handed navigation: the Start and OK/Close buttons. Without these, you can't drive the device with one hand. This, however, can be remedied with a piece of freeware whipped up by some dedicated coders from the enthusiast website XDA-Developers.com, which allows you to use the phone keys for double duty by pressing and holding them. A pity that this wasn't included with the device out of the box.

The keyboard and screen are mounted on separate parts of the device, allowing you to simply slide the display to one side and reveal the keyboard. Doing this automatically switches the system to landscape mode. The keyboard is backlit for use in low light. While the illumination isn't the strongest, it is more than enough to see what you're typing, which is the general necessity. The keyboard works quite well for text input--you can simply pick it up and go without much of a lag or learning curve in how to use it, and for the most part it's very comfortable.

One thing I don't understand is why softkeys are such a hard thing on these sliding keyboards. The Apache had them poorly illuminated and stuck in the top corners of the key board. The Wizard has them poorly illuminated and sandwiched between the top row of keys and the screen. Are we just cursed to have poor softkeys when in landscape mode?

As an added refinement for landscape mode, the Wizard design has two buttons placed on the "top" of the device, where they can be activated by the left hand.

Overall, the 8125's design is very unremarkable, but mostly solid in its execution, and the main deficiencies can be remedied in software.

Despite it's relatively slow clock speed, the 200 MHz OMAP processor in the 8125 does a very good job of keeping things on the tracks. I experienced very little in terms of noticeable performance difference between the 200 MHz 8125 and the 416 MHz Apache. Some of this is due to the fact that the OMAP has additional signal processors which can be used for phone functions, thus keeping the main CPU free to handle the rest of the system.

Regrettably, the 8125 doesn't come with the new Messaging and Security Features Pack from Microsoft. The MSFP is the long-awaited Windows Mobile 5 upgrade that will enable true push email from an Exchange server. The pack was delivered to licensees late last year, but many are still "testing" it. Cingular has committed to delivering this, but they haven't said just when.

If you're daring enough to reflash your 8125 with a ROM meant for one of the other Wizard variants, you can add the MSFP yourself, but this is considered an advanced technique and could result in turning your Pocket PC phone into a paperweight if not performed correctly. Most users are advised to wait for the official update.

Like many GSM Pocket PC phones, the 8125 comes with a Java environment, for running simple "midlet" applications made for conventional phones. Examples include Google Local, Opera Mini, and many other Java-based applets.

There's nothing particularly remarkable about it, but the 2.8 inch LCD provides good quality brightness and coloration, and is more than suitable for most things. Being only QVGA, it's not great for web browsing, but mobile pages are more than adequately rendered.

The 64 MB of RAM and 128 MB of flash memory in the 8125 is becoming drearily standard for Pocket PC phones. As much as I wish that we could get some slightly more interesting in terms of memory, the currently commoditized quantities have the small virtue of being cheap. Out of that 128 MB of flash, the user gets 43 MB straight out of the box, a pathetically small amount all things considered. It's sufficient if you only intend to be handling a few documents, email, and maybe some photos, but any real heavy lifting in terms of databases, music, reference material, etcetera, will end up requiring a memory card.

It's not exactly small, but the 8125 is a definite improvement over some of its predecessors, such as the SX66--also known as the "slabphone." It's also comparable in size to similarly specified devices like the Treos and the HTC Apache. You can, in fact, actually hold it up against your head without feeling like a moron, but most people will still prefer to use a Bluetooth headset or handsfree system.
