Having a dedicated numeric keypad can be a lifesaver occasionally, and while a dedicated pad with real keys is the best, a little application can turn the iPhone or iPod Touch into an impromptu one as well. The Numberkey is only $1.99 and utilizes WiFi (really? no Bluetooth) for the 18-keypad connectivity. Four skins (after the jump) come with the app so you can match up your new keypad with your notebook’s keyboard. Nice.
