Firmware 3.1 Encryption Causing Problems With Older iPhones
Apple has been pushing for iPhone adoption heavily with enterprises and to ease their concerns, the Software and Hardware have become more robust and more IT friendly. Hidden amongst these features is the iPhone 3GS’ ability to encrypt data from the phone itself and while it may (or may not) be suitable for your needs, it has caused a generation gap with previous iPhones as some corporate users are slowly finding out.
Since Exchange support was added to the iPhone and more recently Snow Leopard, corporations have been quick to jump on the Apple bandwagon. While adoption may be up for Apple, costs can often be an inhibiting factor or even being leery of the 3GS’ new feature set can stop some upgraders dead in their tracks. Whatever issue it may be, those users are learning pretty fast that upgrading me be a lot more viable so they can continue using their iPhones in the enterprise thanks to the recent 3.1 Firmware update. What’s changed in 3.1 is that Apple is enforcing encryption flags between the iPhone and exchange servers.
After upgrading to Firmware 3.1 and syncing with an Exchange 2007 server that has encryption enabled the following message appears on non 3GS iPhones:
“Policy Requirement - The account [account name] requires encryption which is not supported on this iPod/iPhone.”
