Thanks. I will try that.

Now that I have soldiered the middle pins of the USB, will it work for the iPhone 4. My friend has an iPhone 4 and I wanted to check in his phone.

Yes I checked. The voltage drops when I connect the phone. Is that a good sign?

Also, with the current setup (soldering the middle two pins of the USB), will this work for iPhone 4? My friend has an iPhone 4 and I wanted to check if this will work.

I'll try to test this with new batteries.

That is a sign of weak batteries. The phone is probably dropping out of charge mode because the voltage is too low. Using the right batteries makes a big difference. Check our battery recommendations here: http://forums.adafruit.com/viewtopic.php?f=15&t=22377

Yes. Older phones had proprietary ways of wiring these pins for chargers. The new USB standard (followed by most manufacturers) calls for the pins to be connected together.
