iphone not recognized after upgrading to itunes 8.2

I dont know whats wrong with iTunes 8.2. Sometimes my computer sees the phone in iTunes, other times I get the error of not being able to sync. My backups take 4x as long now. I reinstalled iTunes and still had issues. My iphone is running slower. I had this problem with the 2G in July of last year. I know its not my computer because i just upgraded it before the 3.0 software! Before the upgrades, i didnt have a Video Card, HD TV connected, a 1 TB HD nor 4 gigs of memory. I know that cant be a problem!

Ok, I've found a workaround on another thread ( http://discussions.apple.com/thread.jspa?messageID=9658855).

According to that poster (he has an iPod Touch), Apple Tech Support told him to disconnect his computer from the Internet, and then try to connect his iPod Touch. This worked for him. I just tried it and it works reliably.

After reading the post I plugged out my Internet connection from my laptop, and then connect my iPhone. It was detected. I repeated this 4 more times and each time the device was detected and came up in my iTunes sidebar. I then restarted my machine and tried it again 5 times. It worked all 5 times. When I reconnected my machine to the Internet, the problem came back the very next time I plugged my phone in.

I'm on a relatively new Imac Intel 2.8 ghz core 2 Duo running 10.5.7. After upgrading my 2G iphone to 3.0 and the Itunes to 8.2. Itunes doesn't recognize my iphone nor my ipod touch. It won't even recognize my wife's iphone 3G running 2.2.1.

I upgraded itunes on my powerbook G4 and there is no problem. In fact Itunes boots up much faster on my old powerbook with nearly the same library as my new intel mac. The iphone and ipod touch will charge through the usb ports on my imac but no joy on itunes 8.2. I've reinstalled, repaired disk permissions, changed usb ports and cables. Seems like it's a goofy bug in itunes 8.2.

I've been a die hard mac fanatic for years but this upgrade of the iphone OS and Itunes has blown the wind out of my sails. Sure hope Apple figures this out soon.

After an embarrassing amount of time troubleshooting this issue, it was as "simple" as the network disconnect to finally get my iPhone recognized.

I understand that Apple has a significant amount of work to get their hardware to work with the effectively infinite number of PC configurations out there, but this seems like a pretty basic bug affecting a large portion of the user base. Hopefully there's a quick fix on the horizon- it's pretty inconvenient to disconnect from the world just to backup and sync.
