> We used to be able to send files over Bluetooth before the iPhone came out. Cross platforms, really? So for example between a Blackberry and a Windows CE phone?
Yes, even "dumb" phones could share files with computers back then. Apple users have no idea how much harm their masters have done to society.
Phones other than iPhones can still share files with each other and with computers using Bluetooth. But people instead use apps like WhatsApp or e-mail for file transfers, even in places where iPhone's market penetration is near zero.
