By rummaging through the bowels of their site, administrators of the Boy Genius Report site discovered the presence of connections from an iPhone with firmware 3.1.3 and a second one 4.0.
Even if iPhone OS 4.0 (the next firmware, note) should logically Being made available at the same time as the new iPhone 4G, it seems that Apple has already entered the beta test phase.
Regarding version 3.1.3, it is a safe bet that it should be available soon.
We discuss it on the forum.
