At first I was raring to have this smartphone. I will not go into the technical details, which were already described in the recessions. I have the 3GB version and am satisfied - no more, no less. The battery delivers what it promises and how stressed his cell phone. What I did not like so much, it seems to me that since this mobile I have poorer reception and also the reception breaks as I knew it before. In many forums, it is said that one has no HSDPA + more, only normal HSDPA, the next higher would then LTE, but if you have not the tariff - one only has HSDPA.
