I actually did just that but because I'd gotten 3 replacement NxS and they kept having issues. I had mine for a year and loved it, got the JB update which is fantastic, but it was giving me nothing but grief. The GS2 is bigger, faster, has significantly better battery life than what I was getting. I've had mine since Thursday and am loving it so far, if having to get used to ICS again and how it looks completely different on the GS2 than it did on the NxS. Frankly, I think it's a major step up. This phone is way faster with much more room to play, both internally and externally. I love that I can add an SD card to make it that much bigger. Thinking of getting a 64gb for my music, might just stop carrying my iPod, too...
