Engadget is reporting that an internal model number (N89) for an as of yet unreleased iPhone has been found in the new iPhone SDK 3.2 that was released at during the iPad launch.

Buried way inside the platform simulator lies a set of folders dedicated to specific models of iPhone OS-ready devices, including the iPhone 3GS, second generation iPod touch, something called the “K48″ (yep, the codename we were told was the internal name for the iPad), and… the “N89.” Sure, it sounds like a Nokia phone just waiting to happen, but this is — according to our extremely knowledgeable and trusted sources — likely the codename of the next iPhone (previous versions were called the M68, N82, and N88).

Another number (N80) was found in Apple’s recently released iPhone OS 3.1.3 and supposedly belongs to an as of unreleased iPod touch model.

Interestingly, Apple’s just released firmware (3.1.3) also includes another new model, the “N80,” which we’re told will most likely be the next version of the iPod touch.

For what it’s worth, it appears the iPad has an internal model number of “K48″. Historically, Apple offers incremental revisions to their consumer electronics lines of products every year. In short, we already have a gut feeling these updates are on the way, the numbers just prove that Apple is in fact working on them.

Toshiba has introduced a new 64 Gigabyte embedded NAND flash memory chips. This means 64GB of data can now be held on one chip, and is expected to begin production in the first quarter of 2010.

The largest capacity iPhone holds only one NAND flash module(space consumption due to cellular hardware ) at 32GB of storage. The largest capacity iPod touch however, can hold two of these chips bringing total storage to 64GB on current high-end models. This means if the 64GB chips are used in iPhone and iPod touch revisions, they could potentially hold 64 and 128GB respectively.

We have reason to believe these chips will make their way to Apple products, because Toshiba introduced 32GB chips early in the year, and they made their way into the current iPhone and iPod touch models.

9 to 5 Mac is reporting that they have received information claiming Apple is developing an FM radio Application to the iPhone and iPod touch. Reportedly, this application would be very similar to the FM radio functionality featured in the new iPod nanos, which is to say the user could pause music, and tag the songs to later find them in iTunes.

Additionally, the FM radio application would be able to run in the background, while other applications are being used. It is not known if the radio functionality would be integrated into the ‘iPod’ application or would be its own standalone application. Also, the song tagging feature rumored to be included in this functionality, would supposedly integrate directly into the mobile iTunes store for quick purchases.

The holdup on this app is that Apple is trying to integrate the Mobile iTunes Store purchases into the functionality of the program. For instance, if you like a song you are listening to on the radio (and that station supports tagging and you are in the US), you will be able to push a button and see the song (and all of the information around it) in the iTunes Mobile store.

The Broadcom chips already built into each iPhone and iPod touch are capable of FM radio reception, so Apple could theoretically implement this feature with relative ease.
