OK here is the real deal on the Lenovo K3 Note for anyone in the U.S. brave enough to try anything. First off Lenovo makes awesome computers that is why they have been building the IBM think pads and think centers forever.
Lenovo does not market this phone in the US and does not support its use in the US, for good reason it is a GSM phone so you are already limited to use with ATT or T-Mobile.
Next it does not operate on the correct frequencies to get anything other than 2G( in the U.S.), which means you can talk and send texts but you will not be using any of the Internet, data or web app functions of the phone unless you are hooked up to a wifi connection.
Next for those of you who are brave enough to try it anyway, I am still using it on an ATT MVNO( Puretalk) and the voice and texts are fine, and Im OK with wifi Internet only.
Next is the issue of the spyware/bloatware/malware that comes loaded on the phone and is really a major irritant for anyone who doesnt already have a big brother named Communist China. If you want to use this phone for yourself, you will seriously have to flash it( In computer speak thats reformat the hard drive and install a new operating system) . Its a simple process if you know what you are doing and since most people wont, there is an excellent on line tutorial by a young man with a great sense of humor who does such a good job of instruction that a 3rd grader could follow the bouncing ball. I would advise using the Adroium OS( which will be in the download files provided with the instructions) .

Whatever you do, dont trash the phone it will have a resale value at or near its original purchase price for probably a couple of years. It is every bit as good a smart phone as the iPhone or the Galaxy in the right market, so just because you cant get max use out of it in the U.S. doesnt mean you cant sell it via Amazon or ebay to a customer in China or India.
