Hi! I know that this issue was discussed not that long ago but there was no definitive answer regarding what can be done to solve the problem. I have what was promised to be "Factory unlocked iPhone 4", which was purchased from a seller in Australia (online), but the Phone itself is probably of Canadian origin (MC605X/A). Seller promised that the phone would work with any SIM... When I tried to activate it with my Israeli Cellcom SIM, that was cut to fut from regular SIM, I've got the message that my sim is not supported... Thinking that cutting the SIM I managed to cause some damage, I've got another SIM (U-micro-SIM) from my cellular provider, but I'm getting the same message again and again. I'm using iTunes version 10.0.1.22... Any ideas what may be the problem? ThankS! Michael.
