I've had LTE for the pass year and a half with the S2 Skyrocket, S3 and now with the 4. Live in Manhattan, can't go back to anything less then LTE at this point (AT&T)
I got the flip case for free from AT&T the day I bought my S3 but after a while it gets really annoying. I got the Defender which I really wanted so I stayed with the Flip case till places started having them. The rubber around the cover peeled off and like some have said it offers no protection...
Same thing happened to me. Went to 2 Best Buy's in the city that had them "in stock" but when I get there they couldn't sell them. Then the guy at the Union Square's best buy told me to pre-order it for store pickup just like they told you which like you said isn't available -_-
So my skyrocket fell and my screen inside is damaged :( I go to AT&T to try and see if I can get an S3 and low and behold they sold the last one they had about 15 minutes before I arrived. Mind you that I called around 15 AT&T's and BB's in my area and the one that had it sold it before I got...
