Its fairly easy to upgrade Wits with latest firmware, here is how:
1. Install the USB driver for your device onto your PC. You can get the driver for Windows PCs here.
2. The Java SE developers kit.
3. The Android SDK developers kit.
Download and install those three applications, and you’re already halfway to taking screenshots with your Android quickly and easily. After you set up the Android SDK developer kit, you’ll be presented with an update screen that probably has an error saying you need to force download. Just cancel/close that screen and continue to the procedure below.
