Siri isn't known for having a winning personality, but a new jailbreak tool can help you give her some pizzazz. The Siri Background Cydia Tweak allows you to spice up Siri's old boring grey background with new wallpaper. Just use any picture from your Camera Roll to change the background, and it will seem like you have an all new personal voice assistant.
As you can see from above, Cult of Mac wallpapered her with snowmen. The tweak can be downloaded for free from the ModMyi repository. It also works with the iPod touch via Spire but doesn't support the iPad.
