Why does everybody get so worked up about this?
The 4G network only became available recently, Belgium can hardly be considered a big market (it's just small in terms of number of people) and apple does not prevent you from buying any other phone that supports the 4G immediately.
I know it's quite ****** not to be able to use the network, while you know your phone can support it, but I'm sure they'll update the carrier settings soon enough and you know when you buy any apple product that you will be part of their 'controlled environment' in many ways... probably the most annoying thing in their policy... but as long as they provide us with the best products in the market (in terms of design and usability in general) we'll keep on buying them and have to accept their policies...
It's just the way it works people... shouldn't surprise anyone and I hardly think they'll be trembling on their feet because of some lame threats made on this forum.
Be patient and in the mean time get a life ;-)
