A new way to annoy your iFriends...
Sending just three emoji to an iOS device is the new comedy hack in town, as receiving the odd visual message combination can lock up iPhones so badly that they need a restart. If you hate someone enough to want to deprive them of a screen to look at for a few minutes, here you go.
