Hi - I have an exchange email account setup on my iphone which requires a rather restrictive passcode lock timer, 15 minutes max. I'm looking for a way to extend this to 4 hours instead. I know of tools such as "Exchange unlock" in cydia, but I'm not looking for a complete disable, rather to allow more flexibility in the configuration. I also tried a solution posted in the following blog post, but it worked for while until it stopped working suddenly (I guess the exchange server pushed settings was changed), removing and reinstalling the configuration file did not help. I looked extensively in the plist files on my iPhone and came up with nothing that works.

There are few older posts on this forum that deals with this topic, but none of them work on the new iOS4.

Any help is appreciated.

Thanks.
