iPhone OS 2.2 Crashes when I Receive Calls

iPhoneAtlas.com listed some problems users were having when upgrading to iPhone OS 2.2, but I've been experiencing a problem not on their list.

I'm not sure if I'm an isolated case or not, but since installing iPhone OS 2.2 on my 3G iPhone I've experienced several crashes when receiving phone calls. The crashes occur mostly when I'm using various 3rd party applications, but also while the iPhone is sitting in my pocket. The applications will start to quit as if to handle the call, but will freeze halfway through the process. After forcing a reboot I am informed that I missed a phone call. This is pretty obnoxious since the device's primary function is to be a phone and all. I'm going to try a restore from backup and see if that resolves the issue.

I did a backup and restore from iTunes and the problem disappeared.

Actually, I still had crashes after that point -- it just took awhile to happen again. I have a developer license though and am no longer running iPhone OS 2.x. I think the problem might actually have been that one or more of the images I had associated with contacts in my address book were too large. I haven't tested this theory though, since I have not had crashes since upgrading the OS.
