I used another service..IMZDL is by far the best I used IMZDL for the ios 8 betas no problem but I was feeling cheap when ios 9 came out so I went with a different company udid.in to be exact. the second I go to upgrade to beta 2 udid.in had removed my udid and I was back to square one. Out the money no udid registered. IMZDL is the best and dont mess around with other companies. trust me.. it is a nightmare.

Spot on Amazing instructions, fast install. IOS9 now on my 6plus and works amazing. No glitches. Seamless transition!!!!

Excellent!! Excellent!! The ease of registering the UDID and downloading the beta was very simple. I ran into an issue where a link didn't work but I contacted support and within minutes I had a response with a fix and another link to go to. I am very please with the service from iMZDL.

The Best and Fastest! IMZDL is one of the biggest names in iOS betas and device registration, but they closed up shop late last year, which may be tied to Apple’s push to take down services that sell developer slots. Earlier this year the company teased that it is coming back, and now weeks ahead of WWDC it is back in businesses selling iOS UDID registrations. Thank you guys, You guys are the best.

iMZDL is awesome for all Apple Betas! I would truly recommend iModZone Downloads to anyone who wants early access to Apple's iOS Betas and Mac OS X Betas. $8 is an unbeatable price for a UDID registration. I have done UDID registration with them almost every year and they are the best. Thank you iMZDL!
