Have you ever wanted to know the definition of a word without having to perform a Google search or open an app? If you have an iPhone 4S you can use Siri to look up definitions, but older iOS devices are have immediate way to show a definition.
Apple has a built-in dictionary in iOS that’s easy to forget about, but luckily a jailbreak tweak called SpotDict makes it simple to lookup words on the iPhone. SpotDict uses Apple’s dictionary to let you quickly define words from the Spotlight window in iOS.
