Ordered online through my service provider here in aus. We get the international version as LTE is really only available in major cities at the moment here. Having used a few different versions of android I can safely say that ice cream sandwich is the best by a LONG way. It helps that it has a phone that simply doesn't lag.
Im really not a brand loyal person. Im typing this on my iPad now and I have an iMac as my main computer however apple are going to have to do a lot with the iPhone 5 to come close to even touching this.
My thoughts exactly with iPhone 5, as iOS 6 was a big letdown.
As far as the S3, I have heard it feels a bit flimsy and cheap in hand, any issues with that or the overall build quality?
