iOS4 with iPhone 3G Woes, and a Patch

When I saw that iOS4 was out, I did what I always do with my iPhone: I upgraded.  I blindly grab Apple’s upgrades every time.  Sure, I should know better given what I do for a living, but when it comes to my iPhone, I’m just a plain old consumer.

This time, it wasn’t so pleasant. From the time I upgraded, my 3G ran sluggishly and sometimes hung up for minutes at a time.  Today in a meeting at work, one of the folks who was there there told me about a patch that Apple has released that is supposed to help with a problem caused by synchronizing Exchange-based email.

I blindly installed the patch (hey, I’m consistent), and now things *seem* to be running better.  I’ll keep an eye on it, but only for the few weeks that I have to wait until my iPhone 4 arrives.  At that point, this old 3G may become my 6 year old son’s ‘iPod Touch’.

iOS 4: Exchange Mail, Contacts, or Calendars may not sync after update

  • Last Modified: June 28, 2010

    Immediately after updating to iOS 4, some users may notice that Exchange ActiveSync Mail, Contacts, or Calendars do not sync, or sync very slowly. In addition, some Exchange Server administrators may notice their servers running slowly.

    Products Affected

    iPod touch, iPhone 3G, iPhone 4, iPhone 3GS


    To work around this issue, users should install a configuration profile from Apple that increases the amount of time the iOS 4 device will wait for the Exchange Server to respond to its sync requests. For best results, the profile should be installed on as many iOS 4 devices at your company as possible.

    To install the profile:

    1. Use Safari on your iOS 4 device to download the configuration profile. It may be easiest to read this article with your iPhone or iPod touch and tap the download link there, but you may also email the attachment to another email account on your iOS 4 device, and tap the attachment to open it.
    2. Tap Install to install the profile, and enter your passcode if prompted.
    3. A warning message will appear because the profile is not signed. Tap Install Now.
    4. Tap Done to complete the installation, then power off your device and power it back on.
    5. Wait for your Exchange data to finish syncing.

    After installation, the profile will be listed under Settings > General > Profile.
