Hello everyone, I am going through the documentation for generating certificates, UDIDs, and provisioning files so I can run apps on my iPhone. In the documentation it states, "Installing Pre-release versions of iPhone OS To run your code on an Apple device, you will need to install iPhone OS onto each development device and "restore" each device to a development state. Note: Once a pre-release version of iPhone OS is installed on the device you cannot restore the device to an earlier version of iPhone OS. The device may only be used for development and testing purposes until that version of iPhone OS is publicly released. Please DO NOT install the iPhone OS before registering device UDIDs, as installation on non-registered devices will render them inoperable. The public release version of iPhone OS should be installed using iTunes." Should I be concerned about setting up development on my personal iPhone? It says that installing UDID on an existing OS can render it inoperable??? Is this verbiage only for prerelease versions of the OS? I am not clear on this. My basic question is can I set up my personal iPhone for testing and running the application I am developing? If yes are their special steps to take to insure that my phone continues to work properly for my personal use? Thank you!
