Documents seen on the FCC site revealed information about the BlackBerry 8120. This is a quad-band GSM/EDGE version of the recently announced 8130, and has many of the same upgrades, including GPS, 3.5mm headset jack, stereo Bluetooth, external microSD slot, and updated mail software. It does not include 3G, but adds 802.11b/g Wi-Fi to the mix. The user manual also details a UMA client on the Pearl 8120, which could indicate that it is headed for T-Mobile and might be compatible with T-Mobile’s HotSpot@Home service.
