This website is a Scammer. They try to attract people by offering the cheapest price range for iPhone 4, 3Gs, 3G. Very interesting price. But what will happen is after you pay them they will send you a tracking number but it is the wrong one. You will never ever get what you order from them. And they no longer reply to your e-mail. They have changed their website 3 times now before it was www.hkcellpex.com after that www.cellpexhk.com and final one is www.telecomhk.com which is the one that I attach to show it to you all now.
They are based in Hong Kong. Even though there are phone number of their company but when you call them there will be nobody answer your phone.
You can check their website out but don't make any transaction with them. Otherwise you will loss your money and never ever refundable.
Lots of love,
