Internet

Rendering web pages upon WAP 2.0 and HTML markup languages, consumers can use the 7105t to browse weather reports, sports scores, stocks quotes, and travel information. Through BlackBerry Browser, users can also access the corporate intranet using BlackBerry Enterprise Server supporting HTTP and IPPP protocols. While Internet Browser renders standard HTML pages as if the 7105t was a desktop, users select the configuration that is optimal for the type of content they are viewing.

Unfortunately, one of the major disappointments in the 7100t was not updated in the 7105t; the lack of EDGE (Enhanced Data rate for GSM Evolution) broadband connectivity. Unable to utilize T-Mobile's high-speed network, consumers will be limited to GPRS (Class 8) for transfer speeds of up to 40 kbps. Although the rates are the same, the 7105t loads data noticeably faster than the 7100t, possibly due to software improvements.

Storage

The BlackBerry 7105t dynamically shares 32 MB of flash memory and 4 MB of SRAM among all programs and processes. While it should be enough for text-intense business users, should more room be needed, consumers will need to clean out old files; the 7105t lacks an expansion card slot.

Connectivity

Supporting "Audio" and "Voice" Gateways, the BlackBerry 7105t can pair with Bluetooth headsets and car kits within a 10 meter radius. Dial-up connections, OBEX file transfers, and Bluetooth syncing has been restricted, but through the supplied USB data cable, many of the restrictions can be performed.

Conclusion

Building on the already popular 7100t, the BlackBerry 7105t adds improvements and upgrades that plagued previous users. More of an enhancement rather than an actual successor, the 7105t has the same hardware while keeping the majority of the features.

However, the small upgrades add up to big improvements. Items such the improved scratch-resistant LCD, more efficient and faster loading web browsing, larger Send and End keys and more accurate predictions using SureType, are not trivial. And adding capabilities such as pushed Yahoo! Mail service is completely new.

But EDGE high-speed connectivity was noticeably missing. With devices entering 3G, it's a surprise RIM didn't decide to include it. Perhaps the only signifcant letdown, the 7105t may be the best BlackBerry to date, improving many shortcomings the 7100-series contained. Initially priced at $200 with a service plan, the value is is hard to beat for a robust business device.
