Hi everybody again!
So, advices here helped! Thanks!
After some research and testing this solutions seem to work OK:
I have only one!! writable sqlite db. (implemented using singleton as
some people suggested here)
Also, I've got some db code to synchronize write operations.
Only one thread can execute write transaction at one time. But I don't
care about opening Cursors and reading from them.
This solution works perfectly after some testing.
