    1. Download your file with +[NSData dataWithContentsOfURL:].
    2. Close sqlite DB, if opened.
    3. Remove old DB file (may be just rename – if something went wrong with downloaded data, you may revert to prev. version of a DB faile) with -[NSFileManeger removeItemAtPath:error:]
    4. Write downloaded data to a DB file with -[NSData writeToFile:atomically:].
