Hi, I bought an iPad 2nd generation from a Cash Converters store about a month ago. I am now trying to sell it on ebay and have been asked if it is locked or not. I have no idea what they mean. I know what it means for a mobile phone, but I know nothing about iPads. There doesn't even seem to be a place for a sim card. I wasn't even aware you could make calls from it, though I have seen the option for facetime. I have read numerous posts on this site and others about the subject but still don't really understand how to tell. There is no option under 'settings' for carrier information as there is on my iphone, so I am unsure where to look. I have only ever used it via my home wifi connection or paired with my iphone via the personal hotspot. I would appreciate any advice please. Also, I am in Australia, so don't know anything about the verizon and AT&T that I have read on here.
