Back in September we had written about a cool mod that brought the glowing Apple logo like MackBooks to the iPhone.

While we didn’t hear back from folks at iPatch who had first announced the mod, K.O. Gadget – a Chinese manufacturer has started selling mod kits that brings glowing Apple logo to your iPhone 4S and iPhone 4.

The mod is quite simple. All you need to do is replace the back panel on the iPhone with the included rear panel with the transparent logo (so that the light is visible through it) . The logo lights up:

whenever front screen turns on, but stays on for 15 seconds after front screen is turned off!

while you are holding the phone up to your face and are having a phone conversation, even when front screen is turned off.

when there is an incoming call, an SMS is received or the phone alarm is ringing

if any background applications are detected to be sending or receiving data during the iPhone’s standby mode

Stays on indefinitely while charging

K.O. Gadget claims that the mod does not have any noticeable impact on battery life.

As you can see in the vide0 below, the mod seems to be quite easy to install. Here’s some of the things that you need to install the mod:

Phillips-head Screw Driver (included in the kit)

Pentalobe Screw Driver (included in the kit)

3M sticker (included in the kit)

Forceps (included in the kit)

Scissors

and follow these instructions:

Remove the 2 screws flanking the iPhone’s dock connector port

Slide open and remove the rear panel

Remove the 5 screws near the flash

Lift up the power connector of the screen

Position the light panel, then connect and mount it using the 3M sticker (details will be provided after purchase)

Replace the 5 screws near the flash

Slide on the included rear panel with the transparent logo (so that the light is visible through it)

Replace the 2 remaining screws flanking the dock connector port

K.O. Gadget is currently selling the mod kit for only $42.90 instead of $79.90. However, if you may need to hurry up as the website says that the offer is available only for the next 19 hours (at the time of writing this post).
