T-Mobile Confirms 3G iPhone in Austria?
Few other details are provided and there appear to be no other reports of this press conference online. Meanwhile, Fscklog.com contacted T-Mobile Austria and their reply was (translated) "Yes, we plan to bring the iPhone with UMTS-support to market, but can't and are not allowed to say when yet."
