I just updated my iPhone 3G to version 3.1.3 via iTunes. My phone rebooted and remained booting for over 20 minutes. Not good. It finally “came to” and upon trying to access the iTunes store to download new podcasts, I got the dreaded:
Poo. Then I tried to open iNews, my RSS/news reader of choice. It started to launch, then crash. I tried disabling Wi-Fi and using the 3G network…I still couldn’t connect to the iTunes store. I launched Safari…OK. I launched the YouTube app…OK. I launched Pandora…crash. See a pattern here?
All third-party iPhone apps were crashing. Frick.
So, I tried the solution offered up by bhuser (deauthorize computer, restore iPhone, authorize computer, set iPhone up as new device, then sync) and all was well. Third-party apps now worked but I lost all of my preferences. Lame. I then Ctrl-clicked (right-click) on the iPhone icon in iTunes and selected “Restore from backup.” Thankfully, this brought all of my photos, preferences, etc. back onto the phone. Jesus.
This issue was likely caused by recently adding a friend’s iPhone app (that he purchased) to my phone. This required adding my computer to his list of iTunes store authorized computers and syncing the shared app to my phone while he was logged into the iTunes store on my computer. What a mess.

Check this workaround found on Apple support website.
It worked for me:

Yep, that works. I would definitely follow the advice they give in the knowledge base article:
“Before attempting these steps, transfer all iTunes Store and App Store content on the device to your computer.”
