With every new firmware version there are bound to be a few bugs here and there. No one was prepared for the issues that users are currently reporting in the iPhone firmware 2.2 update. Some of the more serious issues include the loss of the ability to sync with iTunes, loss in both 3G and Edge signal strength, loss of Wi-Fi connectivity and the disappearance of both Apple and third party applications.

Needless to say this is a huge problem that in come cases make this update more harmful than helpful. A number of users are downgrading back to firmware 2.1 in order to resolve the issues. We ourselves have experienced a drop in signal strength. The most reports we have been getting is loss of Wi-Fi connectivity. Users are unable to get a Wi-Fi connection even without network encryption.

Here are some of the reports that users are making:

• “When I upgraded, all my apps non-original apps disappears, except for google! When I tried to re-download and then resync them onto my iphone, only some of them would appear. After talking to support, we tried starting my computer (she said this was happening to some people) and then syncing. This added a couple more, but about 10 were still sitting in my itunes and refusing to sync.”

• “After the os 2.2 update. Safari suddenly disappeared. Syncing etc didn’t work or resolve the issue. I had to do a restore to get things back to normal.”

• “After upgrading to 2.2 the iphone camera app disappeared, and every program that uses the camera stopped working also. Restoring the phone brought it back but then the next Sync made it go away again. Very annoying. How much QA did they do before they released this upgrade? I can understand third party apps breaking but not the base applications.”

• “I also have had a problem with a missing application. My camera application has disappeared and I tried restoring it, and it appeared for about five minutes, let me take one picture, then was suddenly gone again.”
