Apple has started to make available to international developers its iPhone software developers kit (SDK). Meanwhile, official commentary out of T-Mobile Austria indicates the region will serve as some form of test market for the upcoming 3G iPhone.

iPhone SDK goes international

Recent updates to the text on Apple's official iPhone developers site indicate that iPhone SDK has unofficially launched internationally.

Whereas the site previously stated that "the iPhone Developer Program will initially be available to a limited number of developers in the U.S. and will expand to other countries in the coming months," a message now says that it "will initially be available to a limited number of developers during the beta period."

At least one developer in the UK is reported to have enrolled in the program for £59 ($117), though a screenshot of the international enrollment process suggests the program is now open to 26 other countries in addition to the US and UK.

T-Mobile says 3G iPhone coming to Austria

During a press conference in Vienna on Monday, T-Mobile Austria is reported to have confirmed that a 3G version of the iPhone is on its way to the region.

Specifically, a German-laguage report in derStandard.at states that officials from the carrier said a "UMTS version" of the iPhone would be made available in Austria "shortly," and that the country would be one of just a handful to serve as a "testing" ground for the next-generation device.

In recent weeks, reports have suggested that Italy's TIM and Belgium's Mobistar would also see similar treatment.
