The next episode of the ubiquitous Pearl is now available in T-Mobile stores across the land, bringing the spec sheet in line with the features Sprint, Verizon, and AT&T customers have been enjoying for a little while now -- a 2 megapixel camera, external microSD slot, and 3.5mm headphone jack, just to name a few. Unlike the 8130 for CDMA networks, the 8120 that T-Mobile and AT&T share adds a 802.11b/g radio, but the T-Mobile version packs yet a couple more tricks up its sleeve -- you know, the ones you'd probably expect of any modern T-Mobile phone with WiFi, namely support for myFaves and HotSpot@Home. That last bit about the WiFi calling is where it gets really interesting. Put simply, the experience we had setting up, using, and making calls with the new Pearl linked up to our router was the best we've had so far with any HotSpot@Home device; it definitely seems like T-Mobile and RIM are learning a thing or two about how to make this a truly seamless and painless process. A "UMA" indicator on the display lets you know that calls are being routed over the service, but if you're not paying attention to it, you might never know it's happening -- it's just that good. Grab it starting today for a shade under $150 on contract, or if you'd prefer to keep your money firmly in your pocket, you can still live vicariously through our gallery here!
