Has anyone been able to successfully downgrade a device on 2.1 beta 3 or beta 4 to 2.0.1? A colleague downgraded from 2.1 beta 1 and this seems to be the similar tone with others who downgraded shortly after the 2.1 beta was released, however I'm not so sure that I've read where someone has been able to dowgrade from the later beta releases.
After the DFU mode restore, I get the error stating it cannot activate the device (PIN-Locked).
"The iPhone "iPhone" cannot be used with iTunes because the information required for activation could not be obtained from the iPhone.
Check that the SIM card is inserted in your iPhone and that is not PIN-locked."
I tried a number of times (never went so far as to trying to jailbreak it and activate using a bootloader), however I was able to successfully activate by upgrading from beta 3 to beta 4.
Thoughts?
