Does anyone have an opinion on using Orange or T-Mobile on Austria for the iPhone? T-Mobile costs more - for both the phone and the monthly bill. They offer more minutes, but the plan from Orange gives me plenty of minutes and even more data that I can download (which I care about more). This makes me want to go with Orange (cheaper, enough minutes, more data), but I don't know if there's some hidden thing that I don't know about, since I don't speak German. Such as, is it possible for the 3G network to be slower with Orange? Just an example, I really am not sure if there's a reason to go with T-Mobile since I don't need that many minutes. Any opinions or experiences with either of these in Austria (specifically, Vienna)? Thanks in advance!
