iPhone Firmware Downgrade, Not So Fast

Some early upgraders of iPhone Firmware 1.1.1 who are accustomed to 3rd party applications may be interested in restoring their iPhones to the previous firmware, version 1.0.2.

At the moment, this does not appear to be possible due to the new firmware's use of upgraded GSM modem firmware, which is not downgrade-able by simply applying the old system firmware. More information can be found via this hackint0sh forum thread.

Naturally, we will monitor the situation and provide updates as warranted.
