Based on this Apple Discussions thread it looks like many iPhone 3G and iPhone 2G users who have upgraded to iPhone OS 3.1 that was released yesterday are facing problems accessing their Microsoft Exchange accounts due to device incompatibility with Exchange's server-side encryption.
iPhone 3GS users are not facing the problem as it already supports device-level encryption.
TUAW explains that the issue iPhone 3G and iPhone 2G users are facing is not a bug. They were able to access Microsoft Exchange prior to upgrading to iPhone OS 3.1 utilizing the encryption option in iPhone OS 3.0, but the ability was apparently an oversight on Apple's part. They have actually fixed the security hole in iPhone OS 3.1, which is causing the problem.
“While many are reacting to this issue as though it's a bug, and are reporting it as such, the reality is that the Exchange encryption requirement is a feature and the fact that it was not being correctly enforced was actually a security hole. IT administrators with Exchange 2007 SP1 servers and iPhone clients are probably going to be fielding an above-average level of incoming questions, but at least they can rest easy knowing that Exchange encryption is now working correctly. Cold comfort for their users, though.”
Apple has also posted a Knowledge Base article today to provide more details about the issue. They have mentioned that the only workaround to the problem for iPhone 3G and iPhone 2G users would be to request their Exchange Server administrator to change the mailbox policy to no longer require device-level encryption.
If you are not facing this issue after upgrading to iPhone OS 3.1 then your Exchange administrator has probably not turned on the 'require encryption' flag in the server settings.
Even though Apple has actually fixed a security hole, non-iPhone 3GS users will probably get annoyed with this change as it stops them from accessing email. Ideally, it shouldn’t have worked in the first place but the fact that it worked means, users would have probably gotten used to it.
It will definitely come as a relief to system administrators, but they can expect to get a lot of calls from their colleagues using iPhone 3G or iPhone 2G complaining about the problem.
Did you face this issue after upgrading to iPhone OS 3.1?

This is totally absurd. Yes the 3GS has a hardware encryption chip, but anything that can be done in HW can also be done in software. They are basically just saying f*ck the old device users, as they usually do. What they should have done is to include a software encryption algorithm for the 2G and 3G.
i agree with caco Potoso.. thanks for the information. really very nice posting here.
you said really right i like the video very much. thanks for this.
I think so it is waste for Iphone 3G
I just updated my iphone to 3.1 by mistake
now after the updation, as per what they say that 3.1 can be restored and jailbreaking but that is not the case. I am not able to jailbreak 3.1 software for iphone 3G also.
Please let me know steps of how to jailbreak 3.1 iphone 3G
Thank
updated carrier settings with itunes 9, MMS works for me!
oh, and this phone is not jailbroken..
Another thing about Exchange Enterprise SP1 is that are options to restrict features, like WiFi, add 3rd party mailboxes, blue-tooth, and camera. As well as require password and type of password.
The only part that the iPhone will in-force is the password and the camera. Not sure if the other settings will be added with new updates. But all you have to do is jailbreak, and edit the preferences file to enable the camera or change the password preferences. I had to do this because currently my company miss understand the licensing language on the page.
What I don't understand is why the camera and only the camera?
Dear iphone Hack,
On ma iphone applications botton has red number on it.

Ma yahoo messenger, youtube does not work, why?
Thanks for your answer
You should be safely be able to upgrade to new versions of the iPhone apps.
I have been having issues with my Iphone 3g where it will randomly switch over to the Edge network from the 3G network after the Iphone 3.1 update and it does this at random. There will even be certain times where I cant get signal and I work in an AT&T building. I dont think this is hardware related at all it only happened after the 3.1 update. Do you have any ideas as to why??
