I can verify that cellphone4all.net is a scam. My friend tried to order a phone through that site and they told him that they were having a problem with the credit card processing and could he please send them a money order...yeah, right. Yesterday, I put in an order at the site wiredia.com (formerly known as mobilebee.com)
Buy Samsung I7500 (Unlocked) The site is quite questionable with dozens of negative reviews. I figure I don't have too much to lose since I can just do a charge back. They assured me when I ordered the phone that it was in stock. Today they notified me that the phone is backordered and that there will be a 2-4 day delay. Their online site still says "in stock", so I called them and said that "I would like to order a Samsung I-7500, do you have any in stock" and they told me that the phone was on back order. So at least I have some reassurance of honesty. We shall see...
