As anyone with an iPhone and some unshielded speakers is likely well aware, the two don't exactly get along all that well together when they're in close proximity, with the fight for your desk's air space often resulting in an annoying buzzing sound. Now, one enterprising individual has thankfully come up with a solution in the form of the iPhone anti-interference shield, which consists of nothing more than a carefully cut Red Bull can and some always-handy double stick tape. The shield's creator does warn that there could possibly be some hindrance to your reception, however, although that apparently hasn't been noticeable so far. Of course, then shield would no doubt be just as effective with another 2G GSM phone, and you can probably find a suitable substitute for the Red Bull can if its not to your taste either.
