To access the web through the iPhone costs around 13 pounds a month.
Nick Lee designed a application which at first glance appears to allow users to change the colour of their screen. It was charged at less than a dollar to upload from the Apple iTunes online music store.
However, the application contains a hidden code that allows people to use their iPhone as a modem and access the Internet without paying, the Telegraph reported.
The application was removed as soon as news of its true nature appeared online. Those who downloaded it, however, can keep enjoying its benefits.
"I'm going to use this little gem of an application to my heart's content. I'm typing on it now, and I'm going to see just how much data I can use all afternoon. I was able to get download speeds of roughly 2.5 Mbps," an online user who downloaded the application before it was removed said.
