I’m not sure about anyone else but I’ve been having issues with my Exchange account since upgrading to iOS4 on my iPhone 3GS. Updates are extremely slow and I’m talking, like, 4-6 hour delays. Apple released the following config file last night but I’m still not seeing any improvement. Maybe I should inform the IT guys.
• Navigate your iOS4 device to the following URL CLICK ME in Mobile Safari
• Tap to install
• Ignore the warning and install
• Restart your iOS4 device
