T-Mobile Austria have added a placeholder for the "iPhone 32GB", seemingly a version of the Apple smartphone with twice the storage of the current top-end model.  The handset appears under the carrier's "Coming soon" section, though without any image, detail of pricing or specific launch date.

Clicking on the "Details" button leads to a page with no information about the handset. 

A new iPhone announcement has been tipped to take place on June 8th, at the WWDC 2009 keynote in San Francisco.  Among the expected changes are more storage capacity, as hinted at by this listing, plus a faster processor and a higher-resolution camera (3.2-megapixels compared to 2-megapixels on the iPhone 3G).  More battery life has also been suggested, perhaps as a side-product of Apple switching to an OLED touchscreen.

Update: The placeholder has now been removed by the carrier.
