However, I believe you can put your own certs on an iPhone via the iPhone Configuration Utility. http://www.macworld.com/article/134381/2008/07/iphone_config_utility.html http://www.apple.com/support/iphone/enterprise/ -- ME2 On Tue, Jul 21, 2009 at 7:50 PM, Greg Wright<greg.wri...@wineselectors.com.au> wrote: > This is the best response I have read so far on this subject.
