This unique string of alphanumeric text attached to every iPhone and iPad is the source of a lot of privacy concerns.

    You can’t trust the SYSTEM.

    This is stupid. Apps aren’t being rejected for using this UDID. They are being rejected for not telling the user what they are using it for and asking if it’s OK to use it for that purpose.

    Good on Apple for trying to plug up some security holes that should be handled at the OS level instead of up to developers – another recent example is the thing with Path using peoples phone numbers without their knowledge. This is a good thing. Most online privacy issues can be prevented by common sense. Particularly problematic for many people is seeing how they post personal information on social media, neglect to use privacy settings, and are surprised when their personal information is stolen weeks later. While you can be careful about what you post about yourself, you can’t prevent other people from posting about you. Also problematic for people is how there are sites like http://www.dirtyphonebook.com where people post personal information about each that can’t be removed. With Google making all of this information widely available, being vigilant about seeing what people can find out you is critical to maintaining your online reputation. Big platforms like Apple and Google and Facebook can do a bit more to prevent people from accidentally messing up their own lives by encouraging more sensible defaults, but in the end people have to be smart about what they post about themselves online and take some responsibility for themselves, and this doesn’t solve all potential problems.

  • But there is still a way to get UDID from device without iTunes: http://get.udid.io (because iOS developers still need it)
