Is that for real? I thought people were just joking when they said "all you have to do is just cut your sim down to size"
I do believe Robbers will give those who purchased an unlocked from Apple a hard time in giving them micro sims separate without purchasing the phone from them and resigning another 3 year.
Yep microSIM cards have the same contact pad as a SIM card, it just has less of the plastic around it.
I highly doubt any of the carriers will care where you get your phone from (they make next to nothing from the phone, they make all their money from the plans). They may charge you the $25 or whatever it is for a new microSIM card though if you end up porting existing plans and whatnot.
