3 Mobile and Don't Panic are looking for a designer to create a poster as part of a street ad campaign, and there's a prize of £500 ($900). Mobile Broadband is a service offered by 3 that gives customers access to the internet on their PC or laptop using a USB modem and 3's HSDPA network. Mobile Broadband and dongles are becoming more widely understood but there is still an education job to do to communicate their benefits, and that's where Don't Panic comes in.
