Apple has seeded the iPhone firmware 2.2 beta 2 to developers. This version fully supports the Google street view feature in Maps.app. There were hidden APIs related to street view in Beta 1 but it wasn’t enabled. This version, however, has them fully enabled.
Also, apparently, the seed notes indicate that Line-in audio accessories are now supported in the SDK.
UPDATE 1:
No copy/paste yet again 🙁
UPDATE 2:
Includes public transit and walking directions. Sounds interesting.
