Engadget last night released a list of processors and some unedited details of the new iPhone 3G, as they appear from a private version of firmware 2.0.
The software, probably distributed only to carriers for the appropriate experiments on incoming terminals, contains a series of references which in fact represent a confirmation of some specifications that had already been reported. One of these is the presence of GPS support signaled by the GLL (Global Locate Library) software which is used to manage the A-GPS functions.
This particular type of function (Assisted GPS) often used in cell phones to allow telephones to quickly hook up satellites using a map of their location in reference to the position of the cell. The result is not only faster GPS activation but also less battery consumption. Note that this does not guarantee the presence of a GPS processor in the iPhone, but only the compatibility of the firmware with A-GPS technology. In theory, Apple may not have introduced the chip but only opened the doors to GPS support through external modules, for example, produced by third parties or by Apple itself. Recall that in recent days there had been news from GigaOM of an agreement with Apple with Broadcom for the purchase of GPS processors, but even at that time they had not been able to establish whether the chips were for the iPhone or for others accessory products n if the supply request was sent in time for the iPhone that will be presented on Monday or if for future versions.
The firmware also confirms the presence of the now well-known Infineon PMB6952 base band chip, also known as S-GOLD3, a processor with support for six different band types and UMTS and HSDPA technology. It should be noted that S-GOLD3 to operate on Japanese high-speed networks, and therefore to be useful to Softbank customers, must be supported by a WCDMA coprocessor, which acts as an interpreter for the technology in use in the Asian country.
Among the other details of interest that further confirm the presence of an HSDPA technology a Murata LMRX3JCA-479 amplifier, several RF modules produced by Skyworks (Sky77427, Sky77414, Sky7713), a Sony antenna module with GSM or UMTS switch and the functions of energy saving with the possibility to switch off UMTS.
As for the main processor, the one that manages the entire operation of the phone, nothing changes. This is the 620 MHz ARM 1176JZF already seen in the current iPhone model,
Finally, a detail that seems to contribute to the legitimacy of some rumors leaked in the past. The iPhone 3G is identified internally as the n82ap, a code that had previously appeared in firmware 2.0 but that no one had been able to attribute with certainty to the 3G version of the iPhone. Recall that the iPhone Edge called m68ap while the iPod touch, classified by Apple in the same category, indicated as n45.
