Phone was robbed.. iphone 4 with ios7 I had it set that so when screen locks or gets turned on you need enter in 4 digits. As far as I know I had it synced as I restored it months ago. Now I'm wondering 1) is it possible if they put in new simcard they will be able to use it or see all my data.. or will code be asked to beentered on any sim being put in? 2) Will it be possible for them just to hook it up to laptop and browse into files tru der laptops drive? as in windows it would be like a removable device like usb u could broswe 2 3) Can they backup sync it to another itunes 4) can they bakckup data even if they cant sync it? 5) i bought the phone 2nd hand.. so i cant block the imei as im not originally owner, not sure how that works.. is that depending on the carrier?
