Okay, this is very weird.

Both my wife and I have iPhone 3GS's. We've both just updated to OS 3.1. Now, my 3GS only shows the following choices for the "Require Passcode" option.

  • Immediately
  • After 1 minute
  • After 5 minutes
  • After 15 minutes

However, my wife's shows two more choices.

  • Immediately
  • After 1 minute
  • After 5 minutes
  • After 15 minutes
  • After 1 hour
  • After 4 hours

Anyone have any idea what's going on here? I had mine set to 1 hour, but it's forced to be 15 minutes now, and I totally hate it!
 
Looks like I've found the cause of the "problem."

Description: iPhone OS provides the ability to communicate via services provided by a Microsoft Exchange server. An administrator of an Exchange server has the ability to specify a "Maximum inactivity time lock" setting. This requires the user to reenter their passcode after the expiration of the inactivity time in order to use the Exchange services. iPhone OS allows a user to specify a "Require Passcode" setting that may extend up to 4 hours. The "Require Passcode" setting is not affected by the "Maximum inactivity time lock" setting. If the user has "Require Passcode" set to a value higher than the "Maximum inactivity time lock" setting, this would allow a window of time for a person with physical access to use the device, including Exchange services. This update addresses the issue by disabling user choices for "Require Passcode" values greater than the "Maximum inactivity time lock" setting.

I've just turned off the passcode lock itself. I am not going to let Microsoft dictate how soon I need to type in my passcode to unlock my device!

I saw in one thread where people were complaining that the time was now limited to 15 minutes, so I'm not sure how your wife still has 4 hours.

My post above will explain it. My wife does not have her iPhone connected to an Exchange server.
 
I am not convinced on the exchange connection. a coworker and I both updated last night, both with exchange, and his stayed at 1 hour for the passcode lock, and mine reduced to 15 min. discussed with out IT folks and they had no changes on their end.

See the KB article I quoted in #2. It _is_ related to the Exchange server settings. The Exchange Server side does not have to change anything. It is only that OS 3.1, unlike the previous versions, honours the Exchange setting on the maximum timeout period.

I'd call your friend's case anomaly. :)
 
i think i fixed it

I had a more severe problem - I only had 1 minute passcode and autolock after upgrading to snowlep and 3.1. Apparently its a Exchange server issue with the new software on the phone and Mac.

Here was my solution: i turned on "Fetch" in addition to "Push" for e mail retrieval. To save battery i have fetch at 1 hour. What that seems to do is disable the weird time/security restrictions and adds back all the options for longer times.

I didn't nee fetch at all before but this is a simple workaround, it seems the phone gives you all the passcode and autolock options back when fetch is enabled, and you can still keep push on.

Where exactly did you have "Fetch" enabled? I tried everywhere I could think of, but it had no effect.

I ended up asking the IT guy to change the maximum time setting on our Exchange server. The max is 1 hour (unless you go to "Unlimited") so he set it to 1 hour. I removed and re-added my Exchange account on my iPhone. I can now choose "1 hour." Good enough for me. :)
