1. SL3 unlocking solution exist about 6 months already, but cant be protected from copy/paste.
If GT add it to commercial usage will be free for 2 days, and market killed again for long time.
2. Second solution by code calculation also exist but is very slow for commercial use (same solution as Genie use)
3. R&D department work on new 3th solution protected and commercial, i hope will be offered very soon for GT customers.
