the irony of this. Before i really did searching into the shady practices of AC on eBay, I bought AC from this EXACT seller for my iPhone.
He emailed the code pretty quickly, but his communication was ok and took him a while to leave feedback for me. I did have to utilize the AC on my iPhone a few months later, and i had no problems. I have since sold the iPhone last October.
I, however, bought my AC from the Apple Store. No way am I going to take a risk like that.
For the record, i paid $50 for the AC ( i think it is $70 in the store or something) for the iPhone. This guy is located in Seattle, Washington. Funny he is selling in the UK. I did send him questions after doing research on the eBay scams. He closed shop for a while....
But no one has filed bad feedback though, but the buyers probably just registered it and it worked, thus cannot leave bad feedback when something goes wrong..
