Today, Apple has made the White iPhone 4 available. Apple fans the world over rejoice.

I do mean world too, as it is available in Austria, Australia, Belgium, Canada, China, Czech Republic, Denmark, Finland, France, Germany, Hong Kong, Ireland, Italy, Japan, Luxembourg, Macau, Netherlands, New Zealand, Norway, Singapore, South Korea, Spain, Switzerland, Sweden, Taiwan, Thailand, UK and the US. It’s coming to more countries soon.

As you can see from the image above, it’s amazing. It’s also been very much anticipated, as we previously mentioned. Apple SVP of Worldwide Marketing Philip Schiller said, “The white iPhone 4 has finally arrived and it’s beautiful. “We appreciate everyone who has waited patiently while we’ve worked to get every detail right.”

Apparently that has been one difficult process.

“It was challenging,” Schiller told All Things D. “It’s not as simple as making something white. There’s a lot more that goes into both the material science of it–how it holds up over time…but also in how it all works with the sensors.”

“We obviously think about this in a generic way because you have a white iPad,” Steve Jobs is quoted as saying, noting that the development has been beneficial to other products.

I’m guessing when the iPhone 5 rolls around, it won’t take a year to come in white.

According to one analyst, Apple may sell up to 1.5 million of these White iPhones per quarter.

The White iPhone 4 costs $199 (US) for the 16GB model and $299 (US) for the 32GB model with a new two year agreement.
