Just JB my Original 2G iPhone using redsn0w and that went easy. I installed only Cydia when prompted and that worked fine. I then rebooted and attempted to Unlock my iPhone following Gizmodo's directions and used the repo666 file they told me to add to the Cydia Source List. It unlocked but then gave me the Searching... error then No Service. I tried popping out my SIM and rebooting as well as some Airplane Mode + SIM removal trick from YouTube...no dice. So, I just restored my phone back to 3.0 with iTunes. Anyone know where I goofed on the Unlock? Should I have NOT used the repo666 package??
