iPhone 2.0 firmware, guide
Apple has quietly released the iPhone 2.0 firmware, work has uncovered. Though not officially announced, or yet distributed through iTunes 7.7, the IPSW file can now be downloaded directly from an Apple server. The firmware enables both native applications and access to the App Store; installing it at this stage, however, is only recommended for advanced users familiar with manually synching such updates. A fresh installation of the v2.0 software takes approximately 20 minutes; normal distribution methods should begin by Friday morning.
Apple has correspondingly posted a new guide for installing or restoring v2.0 firmware through iTunes. After installing iTunes 7.7, users are expected to connect either a 2.5G iPhone or an iPod touch. People must then select the Summary tab in the device's Source pane, and click "Check for Update." At this point they can click Update to install the new firmware, or Restore to overwrite with a backup created from a previous iPhone.
