Stuck with one of those non-magical iPhone 4s? Sad that, despite the beautiful retina display, the faster internet speeds, the longer battery life and the 5MP camera, you might experience a drop in signal strength when you hold it wrong?

Then iTape is for you. This innovative roll of Scotch-tape will boost the signal of an iPhone 4 when slapped over the problematic bottom-left corner of the antenna-band. In fact, the tape is simply a roll bought from the hardware store and put up on Ebay, along with the fancy picture above.

The seller, Jason Nolasco, isn't trying to scam you: All proceeds from this practical joke go to the American Cancer Society (or so it says on the Ebay listing). Even if you aren't interested in a $3.50 roll of iTape, you should check out the page just to see the great spoof slideshow detailing its features.

Black available now, white shipping in July (har har).
