This picture is spreading all around the web and rumor has it that the sim tray on the left would be a part of the upcoming iPhone 4G or the iTablet.
It originally appeared on chinaontrade.com who claims that it's an "Apple iTablet iPhone 4 Generation SIM Tray". It would have arrived to their warehouse from Foxconn (Apple's iPhone supplier) this Friday and they are starting to sell it through their website in a couple of days for $14 a piece.
The rumor is growing big and around the web people are going as far as trying to predict the new iDevice's shape based on it (it should be bulkier and more metallic apparently...).
For now it's just a rumor but the part could nonetheless be actually legit, especially knowing that Apple has it harder and harder to keep its new toys secret lately.
