1 star because ...

I received this machine in early AM and tried to open it (I have come to understand the need to remove the shell, which is not absolutely clear since I ordered a phone black to have it on, others more fun colors being delayed for several weeks and the black in the dark ...) to house the battery and sim card. I read in a comment that it was difficult. But the video helped.
I saw 2. They have not helped me. The operation was so fast (and successful) that I did not understand how he should do (I just noticed that the 2 presenters supported on the goal and not the middle of the back). I tried again and again and I decided to drop before the machine (phone without battery and sim card is not a phone, just a machine that is useless) from breaking into two .
In the early evening I again and, miraculously, the bottom of the unit agrees to go out, half, but the top remained stubbornly in place. I'm still trying and again and as nothing comes, I put down in his place, the machine in its box and I decide to go to dinner.
It will be better tomorrow ... maybe.
2 days after the receipt of the machine, painful fingers have both tried, without success, I decided to throw in the towel and I refer the craft.
Too bad, I was looking forward to try Windows Phone and I had the idea, in case of successful test, to drop Android.
