Well, Friday, I traded up to a SGS4 and have never been happier. Loved the SGS2, but it was upgrade time. One thing I thought was ODD.....when the sales lady activated my SGS4, it went to 4G and started downloading data immediately..... I asked her "Hold it, we have 4G here now?" She responded "YES"...for a few months now. My old SGS2 would NEVER recognize that there was 4G anywhere! So, my 2cents, when it is upgrade time, and you're holding out for 4G, just upgrade.....chances are that you indeed do have 4G, the SGS2 just isn't recognizing it.
