'Why' I hear you ask?
Well, I bought the Shadow, brand new, on eBay for $300. That's 150 quid. Shipping is pretty cheap, and although the device is SIM locked to T-Mo USA, it actually takes a T-Mo UK SIM no problem! This makes it an EXTREMELY competively priced Smartphone, and something of a unique choice for a UK buyer. I'm loving it too The same applies to the Pantech. Although my unit is a press device, they can be picked up pretty cheap on eBay, unlocked for a cent under $15, and bring dual keyboard 3G goodness you won't find on this side of the pond.
Check out the videos below, feel free to hit me with any questions about the devices, and definitely check out http://Juno.MoDaCo.com if you're a Shadow owner - i'm tweaking away already
