Now, after the release of 1.1.3, he tried putting his now-1.0.2 phone into recovery mode and updated it to 1.1.3. "It rewrote the firmware, and I now have a fully functional 1.1.3 phone! Yeay! So 1.1.3 firmware must be a complete rewrite. Just FYI, but you probably already knew."
See, TUAW readers? Happy endings do come true! His 1.1.3 phone is back to being locked but it's working again and can be used on the AT&T network.
