AT&T 3125 review: AT&T 3125

The Cingular 3125's external music player controls are a nice touch.

You also get Windows Media Player 10 Mobile--after all, it can't be all about work, right? The 3125 supports MP3, WMA, AAC, and AMR-NB music files (you can also shop for music via the Cingular Music store) and MPEG-4, WMV, AVI, and H.263 video formats.

As a phone, the 3125's address book is limited only by the available memory (64MB RAM, 128MB ROM), while the SIM card holds an additional 250 contacts. For each entry, you can store up to 12 numbers, three e-mail and instant-messaging addresses, birthdays, anniversaries, and more. You can also pair them with a picture for caller ID, a group category, and one of 14 ring tones. As a bonus, the phone supports MIDI, MP3, WMA, AMR-NB, and AAC ring tones. You get a vibrate mode, a speakerphone, speed dial, and voice tags. In addition, Bluetooth 1.2 is onboard for use with headsets and car kits, but like the 2125, the 3125 lacks integrated Wi-Fi, although there is EDGE support.

The Cingular 3125 has a 1.3-megapixel camera with 2X zoom, but there's no flash.

The Cingular 3125 is equipped with a 1.3-megapixel camera with 2X zoom and video-recording capabilities. For still images, you have a choice of four quality settings (Basic, Normal, Fine, and Super-Fine) and four resolutions (160x120, 320x240, 640x480, and 1,280x1,024). And while there's no flash, there is a Night mode under the white balance settings. You also get a self-timer, a time- and date-stamp option, and a photo counter. The 3125's camera records video with sound in MPEG-4, H.263, or Motion-JPEG AVI format, and it offers two resolutions (176x144 or 128x96). We tested the quad-band (GSM 850/900/1800/1900; EDGE) Cingular 3125 in San Francisco and Los Angeles, and overall, call quality was good. On our end, conversations were loud and clear. Our callers reported excellent audio quality and added that they couldn't tell we were on a cell phone. Unfortunately, activating the speakerphone diminished audio quality a bit. Our friends reported no problems, but they sounded garbled to us.

Aside from its phoning capabilities, the 3125 was sometimes sluggish to perform other tasks. There was a bit of lag time as we switched between screens or called up different apps. However, music sounded great on the device and Web pages and video looked amazing on the sharp screen.

The Cingular 3125 is rated for 7 hours of talk time and up to 9 days of standby time. In our tests, we were able to get a good 8 hours of talk time from the phone's lithium-ion battery.
