Apple and retailers around the world began taking preorders for the iPhone 5c at midnight PDT. Now, we’re beginning to get an idea which colored model could prove to be the most popular, or at least the one with the smallest supply available on launch day.

Moments ago, Sprint noted on its website that the 32GB iPhone 5c in yellow “will ship in up to 3 weeks.” So far, a similar claim has yet to show up in Apple’s online store.

Sprint’s entire message to visitors as follows:

Shipping: We’ll do our best to get it to you by 9/20; but because of high demand, some phones will ship in up to 2 weeks. iPhone 5c yellow 32GB will ship in up to 3 weeks. A tracking number will be sent when your phone ships.

We’re going to update this post when additional models sell out. These models are defined as those that can no longer be delivered on Friday, Sept. 20.

Update:

The SIM free iPhone 5c in yellow is officially sold out in both the 16GB and 32GB model. It now has a delivery date of Sept. 25.

As a reminder, the iPhone 5c is available for preorder in the United States, Australia, Canada, China, France, Germany, Hong Kong, Japan, Puerto Rico, Singapore, and the United Kingdom. Both the iPhone 5c and iPhone 5s officially launch one week from today, Friday, Sept. 20.
