Basic Features

Launched on Nextel's iDEN (800 / 900 MHz) network the BlackBerry 7100i offers GPS technology for real-time, audible and visual turn-by-turn driving directions.

Supporting GPS-enabled navigation with TeleNav in the U.S., through assisted-GPS (A-GPS) technology and data service support, customer can quickly get driving directions and update them in real time. Even when the driver misses a turn at high speeds the 7100i immediately shows a new route.

Another feature of iDEN networks is push-to-talk technology. Providing cost effective walkie-talkie capabilities, the 7100i offers the Talkgroup service, enabling instant connection with up to 100 other Nextel users who are on the same Fleet or Nextel Walkie-Talkie network within the same home market. Domestic and international services are available.

One of the reasons BlackBerry devices are popular in business is the unmatched security features. With the proprietary BlackBerry OS, advanced security features allow business users to safeguard sensitive corporate data. Including password protection and keyboard lock, local information can also be encrypted such as messages, address book entries, calendar entries, memos and tasks.

When paired with corporate servers running BlackBerry's Enterprise Server software, the 7100i can even be centrally managed and administered by IT departments. Consumers can securely access Microsoft Exchange and IBM Lotus Domino ISP email accounts, remote address book look-up, single mailbox integration, attachment viewing, and more, all behind corporate firewalls.

Using S/MIME (Secure Multipurpose Internet Mail Extensions) technology an extra layer of security can be added to emails, using public-key cryptography, digital signatures, and writer-to-reader authentication. And end-to-end Triple DES and AES encryption guarantees private information stays secure at all points between the server and the 7100i.

Rating the BlackBerry 7100i's 960 Li-Ion battery at 4 hours and 8 days (192 hours) of talk and standby times, actual times will be slightly less. Handset manufacturers and carriers often list talk-time and standby-time ratings with disclaimers about variable performance and often refer to the times they publish as maximum times.

Screen

The BlackBerry 7100i features a high-resolution color display to view web pages, pictures and attachments in full, vibrant color. Allowing users to comfortably read documents, write emails, and surf the web, the quality of the 65K-color 240 x 260 px LCD was enhanced from prior BlackBerry devices.

Former 7100-series LCDs were prone to scratches, being exposed all the time. Taking notice of the user criticism, RIM improved the display on the 7100i, using a scratch-resistant glass with hard coating. Additionally, with complaints of poor visibility in direct sunlight, the 7100i's screen is brighter and more vivid. Consuming less battery life in addition to being clearer, the 7100's LCD is a much needed upgrade and a welcomed sight.
