Just started using this phone - love having a smart phone, never had one before. Using USB to connect it to PC won't work though - Just says USB device not recognised. I have Kies installed and that Samsung phone studio thing. I've toggled between USB debugging modeon the phone. What can I do? If I do get this working I want to upgrade android from 1.5 to whatever the latest version is. If I do that will I need to re-unlock the phone? Also if I do a factory reset do get rid of data would I have ot unlock the phone again for that as well? Cheers for the help guys.
