Hello everyone as read apps using udid will not be accepted as from 1st may 2013. And we have to use IOS 6 identifierForVendor to get the unique identifier if I am right.But will we able to set minimum deploment target to 4.3? In case devices still running IOS 4.3 or 5.0 how we can cater for UDID, since identifierForVendor is only available in IOS6? Does this mean we use a hash for mac address instead as the Unique identifier? Will that be supporting all IOS versions?
