The BlackBerry Pearl has done wonders for Research in Motion, helping to launch the BlackBerry brand into the hands of normal consumers and not just the business community. The BlackBerry Pearl 8130 provided all sorts of upgrades, but it still did not have WiFi. That’s where the BlackBerry Pearl 8120 steps in, replacing the 3G radio with one that grabs 802.11b/g WiFi signals.
The rest of the features remain largely unchanged, including the trackball navigator, SureType keyboard, integrated GPS, stereo Bluetooth, microSD memory expansion, updated mail software, and the 3.5mm headset jack. Because the Pearl 8120 boasts WiFi, it opens up the possibility of VoIP and VoIP-like services. More specifically, the user manual — which can found at the FCC — makes mention of a UMA client, meaning that it can hot swap (so to speak) between cellular and Internet-fueled phone calls.
Could this mean that the WiFi-equipped BlackBerry Pearl 8120 is destined for T-Mobile and their HotSpot@Home service? Time will tell.
