Is it safe to give out my iOS device's UDID?

Miraz Jordan
From time to time people offer me free copies of their software to
review on MacTips. I received an email today that concluded:

"I'd love to send you an early copy of our app so you can try it out
(all I need is your iPhone/iPad/iPod Touch UDID)."

While I've handed out my device's UDID before now to developers I know
and trust, my question is if there's any security problem for me
handing it out to people I don't know.

Is this UDID something I should protect or can I freely hand it out?

I already assume that it's not safe to install software directly from
random unknown sources…

Thanks,

Miraz

If it is an already approved app the developer should be able to give you a free redemption code for it.

If it is an app not yet submitted and approved what you describe is the standard way. I've never wondered about the security because I'm always the one asking for the ids.

We used the UDID method to give out beta versions of our sword-fighting simulation/game, iSamurai.

I am not one of our software engineers, but I was involved in the process. In fact, I still have lists of UDIDs on my computer, and I can't think of any way to use them for criminal activity.

But there is another way to get a free version for review (after the app is in the store):

Many thanks to both Dougs. :-) This is reassuring.

Cheers,
