I bought one of these about 2 months ago and I gave like 409 for mine, as soon as I got it home I put clockworkmod on it and TNT Lite and I now have the full market place working thanks to this link

My phone is a Nokia E71 on straight talk , you can download a free app to use the phone as a wifi hotspot.
If anyone needs to know anything about this device, I have one in hand.
