we just had a new one happen to us that had not been seen on ipads my husband did not have a security number to open his ipad and someone got in, froze it and wanted money before they would open with a six number code instead of usual four we took it to the shop some how they could only repair it using a lap top but at least he did not lose anything they call it ransome ware and his came up ipad stolen so if something like that happens TOUCH NOTHING take it to your shop and always have a security code
