Not sure, but i believe it's possible, we did get the 4.5 with the notification light bells & whistle ! Isn't our battery bigger also? Im interested in the performance vs. battery exchange for the quad cores. This SII is still powerful & handles every task(s) i throw at it, and i still haven't tried overclocking!
Off topic slightly I'm also enjoying the 4g which is everywhere in the Chicagoland area. It's seems as if cellular technology is trying to live up to a yearly hype! i would've liked to seen more innovative changes to the gs3. Perhaps the razors maxx battery. this should be standard with these smartphones. I also understand that galaxy s a brand / business so they have to move units & strike while it's hot. I'd love to see the quad core in our version, however I'm more interested in its wireless charging feature, and if our u.s. Versions again remove that (I Phone) like ugly center button, before i purchase... Reminds me of a 3Gs
