Ahead of Apple’s new iPhone event on September 9th, Thailand’s National Broadcasting and Telecommunications Commission (that nation’s version of what we know in the U.S. as the FCC) has approved two new iPhone models for sale in the country. The approval was confirmed on Twitter by the country’s Secretary General for these matters, and a local report indicates the model numbers for two new devices: A1524 & A1586.
The model identifiers are puzzling. The current 5s and 5c goes up to A1533 and A1532. It would make sense for the the device labelled ‘A1586’ to be somehow next-generation (as it is significantly beyond the 5s and 5c identifiers). The specification of the A1524 model number is much less obvious. Painting by numbers, as it were, the A1524 should closely resemble an iPhone 5c.
Gurman speculates that the model number could represent variants of the iPhone 5s and 5c, such as antenna tweaks, which probably makes the most sense.
