I speak on behalf of ifixdirect, i would like to clarify somethings in regards to your post. As we said, we were testing a similar approach as KO Gadget to back-light the logo. With our prototype, there were some concerns raised which we have described in that email. We were not referring to the KO Gadget kit in no way at all, in-fact it says so clearly here:
To be specific, the method of actually using the LCD cable as a power source turned out to have negative effects. The reason we referenced KO Gadget because they are also powering the backlight with the LCD cable. In fact if you remember iPatch from the UK who first introduced the mod for the iPhone 4, they were also using the same method as us (tapping directly into the LCD cable to power the LED patch). It is exactly why it required mailing the iPhone in or having a professional background since soldering was a. necessity.
In the end our company wants to steer clear of any confusions or negative relationships. We have ended things on good terms with KO Gadget and there may be future ventures as well. We are just as excited to see their prototype for this mod but wanted our customers to be aware of the issues we faced when developing a similar technology.
Thank you
