Drive + iTunes:
In this mode USB Drive replaces Picture Transfer Protocol (PTP) interface with Mass Storage interface and lets you use the iPhone as a USB Drive. At the same time you can perform iTunes synchronization, developers can use XCode debugger ,etc. In this mode USB Mass Storage will not work on Windows with iTunes or Apple USB Drivers installed.

Default:
This is the iPhone default mode. USB Drive doesn’t install daemon application nor modify any USB settings. Picture Transfer Protocol (PTP) is active as well as iTunes synchronization and tethering over USB.

Drive Only:
This mode is to resolve compatibility issues with Windows and iTunes. In this mode USB Drive changes the iPhone’s USB product ID. This will prevent iTunes synchronization, but USB Mass Storage will work on Windows (and other operating systems). Switch to the Default or Drive + iTunes mode will restore iTunes sync.

There are few paid video recorder available in iPhone. I tried one of them but was not happy with the quality and it takes too much time in saving video to the disk. Recently I tried cycorder, which is available free of cost. I like this recorder as it doesn’t take time in saving video. Quality of recorded video is awesome. You can’t expect better quality than this in 2 M Pixel camera.
To install cycorder, you must have jailbroken iPhone which is running firmware 2.0 or above. Go to cydia search option and type cycorder. Now install it like you installed other packages using cydia.

PDANet from June Fabrics is very popular in windows based mobiles. It allows you to turn your smart phone into Wi-Fi router for your laptop. It is now available for iPhone.

Unlike other software like iPhoneModem, NetShare that tether your iPhone through SOCKS proxy solution, PDANet is true Wi-Fi router. This works seamlessly as if you are connected to a Wi-Fi router. You can share internet to as many terminals you want. You don’t need to configure any settings in your browser or you don’t require specifying any IP address. This is simply another Wi-Fi router.
The only negative point in this app is that you need to jailbreak your iPhone.
