The alleged names for Apple's next-generation handsets were reported on Monday by Japanese Apple blog Macotakara, which also said the lineup will come in the same colors and capacities as the current iPhone 5s lineup. Author "danbo" said he is unsure whether there will be a 128-gigabyte version of the "iPhone 6," which has been rumored as of late.

The details, if accurate, would mean that both versions of the next iPhone will be offered in 16, 32, and 64 gigabyte capacities, with color options of space gray, silver and gold.

The name "iPhone Plus" or "iPhone+" was first bandied about back in January of 2013. Because of a mistranslation from China, the name was originally reported as the "iPhone Math."

Apple introduced two new iPhone models last year with the iPhone 5s and the iPhone 5c. But Apple's colorful, plastic-backed iPhone 5c was essentially a repackaging of parts from the previous year's iPhone 5, and boasted the same 4-inch display as the flagship iPhone 5s.

But this year, Apple is expected to completely redesign the iPhone with two new models sized at 4.7 and 5.5 inches. The larger screen form factors are expected to see the lock button moved to the upper right side of the handset, allowing users to more easily press the button when operating the device with one hand.

Apple is expected to show off both versions of the "iPhone 6," as well as the anticipated wearable "iWatch," at a media event and live stream scheduled for tomorrow at 10 a.m. Pacific, 1 p.m. Eastern at the Flint Center in Cupertino, Calif. AppleInsider will be there with live coverage, and readers can install the official AppleInsider app for up-to-the-minute updates.
