iStores, on the other hand, are everywhere. It's convenient.
Last year I was in London and had a problem with my Nokia phone - it was a total nightmare trying to get support from anywhere. I wasn't looking out for Samsung or HTC shops (obviously) but I do remember at least 2 iStores...
On my 5230 it's a pita to open/sens smses.... on my galaxy si9000 its easy and quick.
only reason I keep my 5230 is for the GPS
