Pretty much mirroring a report from Jeffries analyst Peter Misek last month, Topeka Capital Markets analyst Brian White said today that he expects Apple to release an iPhone 5S in multiple colors in June (via BGR):

Like Misek, who expects Apple to release the next-gen iPhone in six to eight colors, White is expecting Apple to release pink, yellow, blue, white and silver, and black and slate variants of the “iPhone 5S”. Misek also claimed last month that the new device could feature an improved camera, NFC, and better battery life.

White also believes Apple could launch the new model of the iPhone in multiple screen sizes for the first time:

“Our checks are also indicating that the next iPhone will offer customers more choice in terms of screen size,” White reported. “Although Apple offers a 4-inch screen on the iPhone 5 and a 3.5-inch screen on the iPhone 4S and iPhone 4, the Company has never offered multiple screen sizes for a single model. We believe this is about to change with the next iPhone offering different screen sizes that we believe will allow Apple to better bifurcate the market and expand its reach.”
