The white iPhone has appeared in Vodafone Germany's inventory system, according to Engadget.
Last we'd heard, the rarest member of the iPhone 4 clan was tracking for a spring '11 launch -- and that'd line up pretty nicely with shots we've received from a trusted source today showing new entries in Vodafone Germany's inventory system for weiß (white) iPhone 4s in both 16 and 32GB flavors. Of course, this doesn't necessarily mean Vodafone has any idea when these phones are showing up on their doorstep -- maybe they're just preparing (and hoping) that it materializes before too long -- but for what it's worth, the source says to expect a launch "soon."
Apple has delayed the launch of the white iPhone 4 for unknown reasons. It's been speculated that the reason for its delay is due to manufacturing inconsistencies in the white color of its parts.
It's not the inconsistencies of the white parts they're fine I own a white iPhone 4.
There's a issue with the back panel and due to a problem with pictures having a yellowish blur on it distorting the picture everytime you take a picture with flash.
It has something to do with the opacity of the white back panel
Also I found the proximity for light in front panel is weak
Proof here...
