New to this, looking to buy a SG3 & want to root it please help

[zak9494]

Switching over from the iPhone due to jailbreaking dying out. I'm looking on craigslist to buy a Galaxy S3. Im on AT&T and looking to buy a white or black S3. Is there anything specific I should look out for? Also I plan to root my S3, should I look for a specific S3 model and does it matter what version of an OS its running in order to root it? Like the iPhone with jailbreaking.
Any help is appreciated,
Thanks

Make sure you get the US Version over the International version. It has twice the RAM, I believe. The OS does matter when you're rooting it. There are also different instructions for rooting depending on your carrier.
