Does anyone have any experience with udemy.coms classes? Are they worth the money? Have you found udemy classes helpful? I'm thinking of paying for a 2 or 3 hour class in unlocking GSM cell phones to be used on other carriers or in another country. So far I have made a few repairs on some iPhones.

Would anyone know where I can find some free legitimate information on gaining knowledge for something like this. I have already tried YouTube.com and there is a bunch of seedy looking millionaire over night videos. Maybe I haven't looked hard enough

And just to clarify I mean unlocking the carrier not hacking the phone or tablet.

Thanks in advance dwfieldjr[emoji4]
