In your picture the back is labeled "HD7" which is a windows phone. The front does not look like the HD7. That is the problem with some of these cloned phones from China, it is really hard to narrow down exactly what you are dealing with.
"Is life so dear, or peace so sweet, as to be purchased at the price of chains and slavery? Forbid it, Almighty God! I know not what course others may take; but as for me, give me liberty or give me death!"
-Patrick Henry, March 23, 1775
