We featured a line of cases for the iPhone 4 called iTattoo, but this odd customization deserves that name more, as tacky as it is. Made by Sirtified, the iTat creates a permanent etching into the back glass of the iPhone 4 (or 4S). Since the iPhone can’t very well ink itself, you’ll have to play the role of phone tattoo artist. Did I mention that it involves applying an acidic substance to your phone?
As you can see, the iTat isn’t as bad as its name sounds. You also have the option of ordering a custom template, so you can truly personalize your phone. But as I mentioned above, a big drawback to this customization option is that the iTat is a DIY affair. Sirtified will only send you the vinyl pattern and a “Super Magical Etching Fluid” – which is acidic enough that a pair of latex gloves is also included in the DIY kit – and you’ll have to do the rest. Apply the sticker, then the solution. Let it sit for 3 minutes, then wipe it clean and remove the sticker. Afterwards, your iPhone’s glass will be etched with your design.
You can order the iTat iPhone Tattoo DIY kit from Sirtified for $15 (USD); you’ll have to pay an extra $5 for custom text. Replacement back glass not included.
