If I were you I'd rather get Nexus line of phones. Samsung let Galaxy line filled with Network carrier's junk. There are lots of bloated ware on network specific phones. When I look at Nexus phone unlocked with JB it's clean but then there's no 4G LTE.
You can get a factory unlocked phone with no carrier bloatware or just root your phone and get rid of the carrier bloatware. Neither is as easy but it's if you really wanted to.

Amen to that. Hopefully it will be cool looking like the GNex too, the S3 may be a beast on the inside but my god is it ugly
I had the Galaxy Nexus and now I have the S3. I agree the design of the GNex is beautiful but the S3 is definitely better looking (in my opinion). I'm going to be getting the next Nexus too so if it looks like either of these phones I'd be happy
