Looks like iFix is canceling all orders for this.
"Dear customers,
We regret to tell you that our purchasing department has put a recall on all iPhone 4 Light Up Logo Mod back covers due to some concerns that were raised. Our primary concern is that KO Gadget (Our original supplier) has refused to sell the parts to us due to another anonymous supplier obtaining sole selling rights in the US. The current supplier is listed with KO Gadget and you can purchase directly from them. Our company has found Ko Gadgets ethics unprofessional as we have been in touch with them since their first publication.*
With this in mind, we also regret to tell you that there has been a few tests we performed with a similar concept (tapping into the LCD to power the light) and the results were not as positive as we expected. Battery drainage is common, fading of the LCD may be possible. This does not refer to the KO Gadget product line-up as they are using a different module so these issues may or may not arise. There has also been rumors that by tapping into the LCD power, you may also short circuit your logic board.*
We are working right now as we speak to develop a light up module that does not tap into the LCD, rather than the battery it self. This will most evidently provide even power distribution and prevent from any short circuiting or permanent damage to your iPhone 4/S. We are keeping in touch with our current factories in Shenzen on development of this product and more news will be posted.
All of the orders that were purchased were never debited to our accounts, they are pending transactions and all of them will be released today back to your card. It will take between 2-3 days for the money to reflect on your account. Each one of our customers who has already ordered the light-up mod will also get a $15 gift card for all the inconvenience this may have caused you.*
We believe in our customers and our brand therefore we want you to have only the best modification products out there. Many of you have shopped with us before and know that quality and customer satisfaction is our primary concern. With this said, we will be working to create a solution that can work without affecting any components of the iPhone 4/S.*
