On the surface, the BlackBerry 8707g, ready for launch some time this week, looks a heck of a lot like the rumored 8703e that’s been kicking around the internet, but it’s quite a catch on its own. High-speed data junkies will be able to get their fix through the 2100 MHz UMTS capabilities of this unit, which can be exploited as a tethered modem for laptops.

The 8707g latches onto GSM/GPRS networks over four bands (850/900/1800/1900 MHz), and throws down a full QWERTY keyboard (hurray! no SureType!), 64MB of flash memory, Bluetooth 2.0, 320 x 240 color LCD, a built-in speakerphone, and BlackBerry’s usual suite of PIM software.

Push email is here, and attachment viewing is a cinch, with love for JPEG, BMP, TIFF, Word, Excel, PowerPoint, WordPerfect, and PDF formats. No word on pricing.
