How To: Fix iPhone 3G/ 3GS And iPhone 4 iOS 4 Exchange Sync Problem

When iOS 4 was released recently, there were many users (including us) who rushed into the excitement and upgraded their iPhone 3G/3GS to iOS 4. However, soon some quirks were discovered, in addition to the known limitations of Apple’s latest OS on the previous generation iPhones (like lack of multitasking etc.) One of the quirks with this upgrade was that many users were no longer able to  use Microsoft Exchange sync for synchronizing their Mail, Contacts and Calendar entries with their devices. In addition to this, some users who were able to do so complained of syncing at very slow speeds. If you are amongst the users effected by this problem, we have a fix for you. For details and the complete method, read on after the jump.

Losing the ability to sync your mail, contacts and calendar can be a real pain if you have become used to keeping all that information synced across all your devices through Microsoft Exchange sync service. That’s why this issue caused by iOS 4 resulted in a lot of uproar from the effected iPhone 3G and 3GS users. Luckily, the fix isn’t much complicated and in a few simple steps, you’ll get the syncing ability back, with the speed issue fixed.

Here is a step by step guide on how to fix the sync issue with iOS 4:

  1. The first step is launch Safari on your iOS 4 upgraded device.
  2. Now download the configuration profile using Safari.
  3. Once downloaded, tap the “install” tab to install the profile and also enter your passcode if prompted.
  4. Ignore a non-signed profile warning and press “intsall now”.
  5. Once the installation is finished, press “Done”.
  6. Now hold on till the exchange data finished syncing. You can check the profile by navigating to Settings > General > Profile.

And there you go! If every thing went alright, you will be able to sync your mail, contacts and calendar without any issues. Enjoy! =)
