Windows 7: Windows explorer does not read iPhone

Not sure if this is the right place to post this, but I'll start here. I'm running windows 7, 32 bit and I have an iPhone4 with most recent OS. Yesterday I mistakenly shut down the computer while iPhone was backing up/syncing with iTunes. Today when I attach the iPhone, the computer does not recognize it. iTunes DOES recognize the iPhone, just not windows explorer. When I attach my iPad, the computer does recognize the iPad. I did a Windows system restore and a reset of iphone that erased all settings, but that didn't help. Any thoughts? Thanks in advance.

Follow below procedure, make sure that your iphone is connected to your computer with iphone data cable!!
1. Download DiskAid which is a free iPhone Explorer [ Lets you explore your iphone files and folder ]
2. Install and Run DiskAid it will automatically detect iphone and navigate to the camera photos folder on your iphone
Hope this helps
You could also try removing/uninstalling it through Device Manager. Then plug it back into your PC and windows should pick it up as a new device
