Want to downgrade your device to iOS 8.4.1? Yesterday you could, but today you can't.
This is because Apple keeps a tight leash on iOS updates. During the install process, the device (or iTunes, or Configurator, or GroundControl) must verify some information with Apple, specific to both the device and the iOS build. Apple's servers analyze the info, then send back a one-time key to permit the installation. So at any time, Apple can stop "signing" the iOS update, effectively stopping all installs.
(This process doesn't affect you if you are already running the OS, only if you are installing or re-installing it.
After a new release, Apple always shuts down the old release. But it doesn't shut it down immediately. It waits a week or two first. I don't know the exact reason for the "signing window" to stay open. Maybe it's to give extra time for companies in the middle of a large deployment to get organized. Maybe it's to allow individuals who accidentally upgraded too early to change their minds. But when Apple stops signing that old release, it effectively forces your hand, and any iOS install then MUST go to the latest version.
Unfortunately, Apple has never announced in advance when it will stop signing an older release. This makes planning, well, a challenge.
To help (a little), we've compiled a history of how long Apple's kept that window open, after an upgrade. Maybe history will be a guide.

Apple yesterday released iOS 9.0.2, on top of iOS 9.0.1 a couple of days ago. (We forgot to post that!) iOS 9.0.2 patched a lock screen security vulnerability, and fixed a couple of bugs.
Release notes for iOS 9.0.2:
This update contains bug fixes and improvements including:
- Fixes an issue with the setting to turn on or off app cellular data usage
- Resolves an issue that prevented iMessage activation for some users
- Resolves an issue where an iCloud Backup could be interrupted after starting a manual backup
- Fixes an issue where the screen could incorrectly rotate when receiving notifications
- Improves the stability of Podcasts
iOS 9.0.1 had the following to say:
This update contains bug fixes including:
- Fixes an issue where some users could not complete setup assistant after updating
- Fixes an issue where sometimes alarms and timers could fail to play
- Fixes an issue in Safari and Photos where pausing video could cause the paused frame to appear distorted
- Fixes an issue where some users with a custom APN setup via a profile would lose cellular data
Downloads of the latest IPSW for each device is available from our database of iOS Devices.
We use Always-On VPN with IKE 2 to reach our internal networks. Our internal networks can reach outside web servers only via http/https through our company proxy. This worked perfect until iOS 8.4.1. Some users upgraded their machines to iOS 9 and they told us "The internet is not working". We tested it and couldn't see any traffic to our proxies. iPads/iPhones try to resolve DNS and reach the servers direct. But our internal DNS Servers are not connected to the internet DNS Servers.
Just tested the function with iOS 9.0.2.
Still not working ! Very serious bug for company use of iOS devices.
We have been experiencing an issue on our campus where Apple devices, and Apple devices only, are disconnecting and reconnecting to our wireless network.
This has caused huge issues for our teachers who are streaming content to Apple TVs. Every 5-10 minutes the wifi drops, causing whatever they are playing to stop and terminates the connection to the Apple TV.
We've experienced this issue with iPhones, iPads and Macs, both managed and not. We also have Dell desktops, Chrome books, and surface tablets deployed in the school and none of them seem to be experiencing an issue.
My network admin isn't sure where to start trouble shooting as it is only Apple devices experiencing the issue. I do know we use all Cisco Enterprise level hardware for the routers.
Any direction would be much appreciated!
The next phase of GroundControl is beginning. I'm looking for 1-2 mobility engineers to work with me, helping large enterprises implement our software and save them from a world of pain. Must have MDM experience with Apple iOS devices. Best if you live in the New York area, too, but would consider remote workers. We are a small team today so you'd have a lot of impact!
E-mail me at aaron / at / groundctl / dot / com if interested.
One of the most anticipated features of iOS is the ability to distribute VPP apps to devices without Apple IDs, as long as certain conditions are met: device is on iOS 9, app was purchased through VPP, app developer opted in, MDM supports this feature.
What is unclear at this time is WHICH MDM providers support this feature today. As far as I can tell, very few were ready on day 1. Was yours?
Does your MDM support per-Device app distribution? Please post your MDM vendor and your experiences here. Maybe we can get them to prioritize this feature.
I upgraded to Server 5.0.3 yesterday. I previously was unable to sync new VPP purchased apps(Last couple weeks) and apple support said I had to updated before VPP would work again. So I upgraded. I am able to login and the apps are there. But randomly I get grey screen or "A server error has occurred." while working. Usually I get one of those errors instead of the page or button I click. I have monitored the log files after hitting load until I get the error: The server starts running version slow at this time. It is a i7 with 16gb of ram. Any suggestions? Any help appreciated.
(log follows below)
Apple has published their regular inventory of security updates in iOS 9. By my count it is a new record of patches: 107 vulnerabilities.
Apple's been getting better and better at documenting and fixing security vulnerabilities. So please do your part and update your devices!

"You can define a custom Access Point Name (APN) for cellular data access using either of two different configuration profile payloads – APN or Cellular. In iOS 9 you currently must use a Cellular payload for your APN profile. Apple plans to address this issue in a software update."
If you are affected by iOS 9 APN issue please refer to Apple's KB.
iOS 9 contains many new restrictions, especially for devices supervised by GroundControl, Configurator, and DEP.
Over at GroundControl's web site, I've posted a list of the new restrictions, plus sample configuration profiles for each. Want to lock the device name or wallpaper? Prevent the device passcode from being set or being changed? These are for you.
A few of the MDM providers will be ready on day 1, but if your on-prem solution may take some time to update, then you may use these files to bridge the gap.
I have made an App I built with Enterprise profil.
When I deploy this app, I have the error : "The application could not be verified."
AMDeviceSecureInstallApplication (thread 0x10b23b000): Could not install package on device: kAMDApplicationVerificationFailedError
How could I verify the app?
Thanks in advance!
P.S. Sorry for my bad English, I'm just a French
iOS 9 available September 16, new iPhones, bigger iPad Pro, new iPad mini 4, new Apple TV with apps...
Lots and lots today at the Apple announcements. This big one for this crowd is this:
iOS 9 available September 16
It's coming, and hopefully you've been up to speed on Apple's iOS 9 Checklist. (OK Seriously who has time for this?). Apple today not only released the Gold Master of iOS 9, they released the first beta of iOS 9.1. Time stops for no one.
The new Apple TV, available "Late October" comes with "tvOS" and runs Apps. Enterprise Apps are usable too, according to the updated license agreement. Does this mean MDM support for apps to Apple TVs?
Two new iPhones — 6s and 6s Plus — come 3D Touch (new gestures), Touch ID 2 (faster), better camera (12M pixels & 4K video), LTE Advanced and quicker WiFi. And pink.
A new 12.9" iPad Pro, with optional accessories Apple Pencil, and Smart Keyboard for those of you with Surface envy. No, that can't be the case, because Apple put Microsoft on stage to demo Office for iPad just after its introduction. (Which looks very cool using Excel and Word side-by-side.)
In case five iPad models makes your eyes cross, Apple has published an iPad comparison that may help. From what I can tell, there are 23 different combinations of capacity, size, and networking. And I'm skipping color options.
