White iPhone 4 Due In Spring?

We had pretty much written off the white iPhone 4 all together, there was evidence coming in from everywhere and multiple sources claiming that the white iPhone 4 will never make it to our stores. But now it looks like there could still be a small glimmer of hope for white unicorn.
Now it’s only something small to go by, but it could be true….
Apparently placards in Apple’s stores are beginning to pop up with the white iPhone on them, and in the fine print, a brief line saying it will be available spring 2011….
So maybe Apple haven’t written it off all together as we previously thought?
They did say back in October that it was delayed until Spring 2011 but only told us this was because of some manufacturing difficulties, which reports suggest are due to light leaking and affecting the camera.
I guess it’s just another case of waiting to see if the white iPhone comes to light, if Apple were to release it in Spring 2011, it would also be very close to the announcement of the 5th generation iPhone, so I wonder how that would go down?
