Apple makes a lot of big changes to its mobile operating system with iOS 5, dribbling in beta to developers ahead of general release later this year. But there is one big change, some developers are just starting to take notice of that Apple is not to say that much. In iOS documentation last updated 5 (which is only available to registered Apple developers, but a copy was sent to me), Apple said that it would gradually abolish access to unique identifier or device UDID, iOS devices such as iPhones and iPads.
This is a big deal, especially for mobile advertising networks, gaming network or any app that relies on the UDID to identify users. Many applications and mobile ad networks, for example, the use of hash version or UDID to follow their users and what measures they have adopted. App publishers must now create their own unique identifiers to track users, go ahead, which means that they have to throw all their historical user data out of the window and start from scratch.
Here is the language from the Apple Developer documentation:
It is not recommended in iOS 5.0
uniqueIdentifier
Alphanumeric string that is unique for each device based on different hardware details. (read only) (Deprecated in iOS 5.0 instead, create a unique identifier for the application.)
Changes may be in response to the issues of confidentiality, or as a way to warn them. Mobile ad networks, for example, use the UDID of targeted ads. It is not clear whether Apple itself will stop relying on the UDID as a unique identifier for IADS, Playcenter or other services. "I guarantee that Apple will not renounce the use of UDID," predicts one mobile industry CEO. If Apple to continue to use the UDID for himself but denies it to developers who would be "extremely one-sided change." This would give the game Center and IADS has another advantage over competing services of third parties.
If you are a developer of the iPhone, please weigh in with your comments below. How much trouble would cause this change, or is it just a minor annoyance?
Started by Steve jobs, Steve Wozniak and Ronald Wayne, Apple has expanded from computers to consumer electronics over the past 30 years, officially change their name from Apple Computer.
