Hey if there will be a non-contract option, it will be unlocked. Right?
Yeah, you should receive the update before South America too. Motorola is a prejudiced company.
No. Even if you purchase a phone outright here, it will still be locked to whatever provider you purchased it from.
Some providers will let you purchase an unlock code once you have been with them for a certain number of months (eg: 3 or 6 months).
