As I heard, Apple is no longer to support UDID (not really sure)
I'm worry about google analytics, as im not sure will it use UDID for gather data for report
if yes, what will happen if there is no more UDID?

UDID is no longer supported through the app store. I've found that various integrated platforms (similar to Google Analytics) will make an update to their SDK to deal with the UDID issue. I would contact them or check for an update.
True, UDID was deprecated in iOS 5.0.
Documentation (UIDevice Class Reference) suggests using CFUUIDCreate (which you can store to NSUserDefaults for example).
A very interesting solution (querying the MAC of en0) can be found here:
