According to a post on fscklog (English translation here), Apple may use the Austrian market as the testing ground for a new 3G phone. T-Mobile Austria announced on Monday that a UMTS version of the iPhone will be available "...soon" with "more flexible" options. We assume that "more flexible options" refers to user plans.
Last September, ZDNet Australia surmised that their country could be the first to receive a 3G iPhone, noting Apple's timetable for a battery capable of supporting a 3G phone ("...late 2008") and the iPhone's launch date in Asia Pacific. A good guess, but T-Mobile's announcement seems to shoot it down.
If any TUAW readers in Austria can shed some light on the speculation, please let us know.
