My good friend and coworker @reecewilkinson seems to have found a REAL fix for the Exchange 2010 issues with IOS 4. He obtained this profile directly from an engineer at Apple. If you were getting issues (mostly with sending emails), this profile update will likely help you. More specifically, it’s a work-around that disables support for EAS 14 and defaults back to EAS 12.1.
Here’s the exact words on the profile update:
Disables support for Exchange 2010. Exchange 2010 servers will be treated as through were Exchange 2007 servers. NOTE: Requires reboot.
So far, this has yielded huge improvements with our testing. Your mileage may vary. We will be rolling this out to about 200 iphone users in our environment.
Here’s the link (just click with iPhone and install): BlackListExchange2010.mobileconfig
UPDATE: IOS 4.1 works great. It appears that Apple fixed the issue finally. The above fix only applies to 4.0.x and isn’t necessary for 4.1.
Now if we could only find a way to make the actual phone calls more reliable! As a work-around, here’s is the proper technique for holding the iPhone. Note that there is only one contact point with the hand… and it’s well away from the antennae bands.
