The Treo 700wx has integrated Bluetooth for use with wireless headsets and car kits and wireless synchronization with Bluetooth-enabled computers, but the Bluetooth dial-up networking (DUN) capabilities won't be immediately available at launch. (Sprint said it does't have a specific time frame for enabling this function.) Until then, you can use the included USB cable to employ your Treo as a wireless modem for your laptop. Be aware, however, that this will require a Sprint Power Vision Modem Plan, which starts at $39.99 per month for 40MB or $49.99 per month for unlimited.
The rest of the 700wx's features are identical to the 700w's. You get the Ignore With Text feature that lets you answer calls with a text message, photo speed-dial, and a 1.3-megapixel camera. Check out our 700w review for more information.
We tested the dual-band (CDMA 800/1900; EV-DO) in San Francisco using Verizon's network, and call quality was good. Our callers said we sounded great, and for the most part, we had the same comments, although we thought their voices sounded just a tad hollow. Activating the speakerphone diminished the audio quality a bit, but we were still able to carry on a conversation.
As we mentioned earlier, we experienced improved performance with the 700wx over the Treo 700w. The device was responsive as we performed various tasks, even with multiple applications open. We had no problems transferring, viewing, or editing Office documents, and music and video playback were also smooth.
The Treo 700wx is rated for up to five hours of talk time and 15 days of standby time. In our tests, we were able to get 5.8 hours of talk time out of the device's battery. According to FCC radiation tests, the Treo 700wx has a digital SAR rating of 1.26 watts per kilogram.
