When I came to Australia with my American iPhone 3GS (locked to the carrier), I was told that Chinatown was the best place to go to get it jail broken and unlocked. Without any specific recommendations, I ducked into and out of a few shops before I found one that seemed legitimate and capable. Digital Mix is located in the center of Dixon shopping center in Chinatown on the ground level. After talking with the techie inside for quite awhile, I agreed to leave my phone in their hands over night. I walked out of there hopeful and excited to finally be a legitimate person again- an iPhone user- and get to retire my airport-acquired red Nokia. Much to my disappointment, I received a call about 30 minutes later. It was the shop girl at Digital Mix revealing that because of the hardware and software combination on the device, they would not be able to safely or effectively unlock it. CRAP! I picked up my lemon of a phone with discontent and disappointment. Thinking about it, however, I am happy that the shop didn't just go ahead with the procedure and totally ruin it. I have confidence that had my phone been a different version (something other than 4.1), they would have been able to set me up. Unfortunately, I am now left with a fancy iPod that also doubles as a paperweight. read more
