Apple Adds Revised iPhone 4 and White iPod Touch Models to Inventory Database

9to5Mac reports that reliable source "Mr. X" has revealed that Apple has added a number of new entries for revised iPhone 4 and iPod touch models to its internal inventory database.

According to the report, three new iPod touch models have appeared under the codename N81A, which it presumes to be the new white iPod touch in three different capacities. The black iPod touch is expected to continue to be offered under the current N81 codename.

This information lines up with what we reported last week, indicating that only minor updates to the iPod touch are expected. MacRumors can indeed confirm that N81A is the codename for the white iPod touch, and that Apple will be continuing to use N81 for the black iPod touch.

Apple is expected to make the black iPod touch update a quiet one, utilizing the same internal codename and SKU as the current line but with only minor changes such as an improved ambient light sensor and the addition of an oleophobic coating to reduce fingerprint smudging on the device's screen. Our information suggests that Apple has been targeting an availability date of October 13th or 14th for the new iPod touch models, although that has apparently been a bit of a shifting target.

Apple's iPhone 4 revisions appearing in its inventory database are marked as N90A, a minor change over the existing N90 device that is the current GSM iPhone 4. The CDMA iPhone 4 carries the codename N92. Two new N90A models have appeared in the database, with the report suggesting that they are tweaked low-end iPhone 4 units in white and black, potentially coming in at 8 GB. The "iPhone 4S" that has been seen in a number of parts leaks and bearing a nearly identical appearance to the iPhone 4 has been carrying a codename of N94 and has not yet appeared in Apple's inventory database.

One more piece to the puzzle comes from our previous information, which had indicated that Apple was also preparing a minor update to the iPod nano. Our information indicates that the revised iPod nano will carry a codename of N20A, differentiating it from the current N20 sixth-generation iPod nano. Apple has also been rumored to be discontinuing the iPod classic and iPod shuffle.
