I was in the process of managing the iPhone device for testing an iPhone app.
In the Organizer window (inside xCode) I clicked on the iPhone's "Use for development" button and received the following error message:
"The version of the iPhone OS on "iPhone" does not match any of the versions of iPhone OS supported for development with this copy of xCode ...
The OS installed on the iPhone is: 3.1.2 (7D11)
XCode latest possible supported version is: 3.0 (7A341).
------
I am working with XCode version 3.1.3.
------
The problem is:
Currently there are numerous applications installed on the iPhone.
Some of them will not work if I downgrade (restore the device) to version 3.0.
My question:
Will there be any damage to existing installed applications and their data if I restore the device's OS to version 3.0 (for testing purpose) and then, at the end of testing, upgrade to version 3.1.2?
Thank you,
