2. When it is factory unlocked i can safely upgrade to the latest ios without problems and still use with other carriers right? yes, you can upgrade with out issues. You can use other carriers as long as they're gsm.

Just like what PsstGreek said. The unlocking is basically your IMEI number in Apple/AT&T database and is permantly unlocked.
And you can upgrade freely without worry of being locked.
