How to unlock Sciphone?
 

Hello
As you can see this is my first post and I'm a complete newbe to the phones issue, so I could use your help.
I have a chinese clone - I think its I86 but I'm not sure.
Its version is M15PX- gemini, so that might be a lead.
I have a few questions about it:
!. how can I unlock it. it works when I put in a sim of one operator, but when I put in a sim of a second operator- another network- it doesn't work.
2. Is it possible to put "Waze" on it and if so, how?
3. I find that the sensetivity of the screen needs to be increased. is it possible?
Thanx for your attention and help.
