Recently Apple released iOS 4 (the new name for the operating system that runs on iPhones, iPod touches, and iPads). Since its release there have been numerous reports (link, link, link) of a number of issues with new iPhone 4s (and older iPhone models running the updated software version) when using Exchange ActiveSync (EAS) for mobile email. I wanted to put up a quick posting about what issues users may be seeing and what we’re doing about it.
Update 7/1 1:10 PM: We had suggested using Apple's configuration utility to make this change. Apple has informed us that you should not use the configuration utility to edit or install the update. Use a text editor such as Notepad to change the timeout value in the update, if required. The configuration utility doesn't know about the timeout key used in the update.
We have been in contact with Apple about each of these issues (as well as some others that seem to not be directly related to EAS but are more email related in general). Apple has assured us that a fix is being worked on though they have not commented on a release timeline for the fix. We will be continuing to work with Apple to help resolve the current issues relating to iOS 4 using Exchange ActiveSync.
