Hi everyone, I'm leaving in a few months to go to Australia for 4 months on a study abroad. I have an iPhone 4 with Telus, and they now do unlocking of iPhones (according to someone I talked to in-store). If I unlock my iPhone, I should be able to leave my Telus Micro-SIM at home, and pop in a prepaid Micro-SIM in Australia from a cell phone provider there, correct? And when I get home, and switch back to the Telus microSIM, it should recognize it? I'm also wondering if anyone has advice on which carrier to go with in Australia? I'll be living in Canberra while I'm there, but will hopefully travel to Sydney and Melbourne. Thanks!
