Apple releases iPhone SDK Beta 3; code points to 3.5G iPhone

Apple today released iPhone SDK Beta 3 (build 9M2158a) which fixes bugs and adds support for the latest iPhone OS.

This third beta release of the iPhone SDK includes a complete set of tools, compilers, frameworks, and documentation for creating iPhone OS applications. These tools include the Xcode IDE, and the Instruments analysis tool, among many others. With this software you can develop applications that run on iPhone and iPod touch using the included iPhone Simulator.

Aidan Malley reports for AppleInsider, “Hidden away in the latest test firmware for iPhone developers is the mention of the chipset that will power third-generation cellular Internet access in Apple’s next generation of the device.”

“Discovered by the creators of the popular ZiPhone jailbreak and unlocking utility, a small, nondescript entry in the new firmware used to identify the phone’s chipset refers to a device known as ‘SGOLD3,'” Malley reports. “Sleuthing reveals this to be an Infineon chipset, the SGOLD3H… The iPhone currently uses a predecessor of the chipset, the SGOLD2, to drive its communication link.”

The SGOLD3H chipset “not only adds 3G over HSDPA but runs up to the international standard’s newer 7.2 megabit per second spec — twice the speed of the 3.6-megabit access seen on most HSDPA networks,” Malley reports. “It also supports WCDMA, a related 3G technology needed for countries such as Japan and Korea.”

Infineon’s description of the S-GOLD3H chipset verbatim:

With its new S-GOLD3H baseband, Infineon Technologies extends its well known S-GOLD baseband family to support the 3.5G mobile phone generation. The integrated dual-mode HSDPA/WCDMA/E-GPRS modem technology, together with high speed multimedia hardware accelerators and the advanced connectivity options enable S-GOLD3H to fulfill the requirements of tomorrow’s mobile phones.

Infineon is one of the early platform vendors to support HSDPA category 8 (7.2 Mbit/s). The implementation of equalizer based advanced receiver technology improves the data throughput, especially at high data rates, by up to 40%. In addition, the software programmable slot processing in the HSDPA Rx path provides further flexibility for performance enhancements. The HSDPA performance of S-GOLD3H meets and exceeds all test cases as specified in the 3GPP standard. Infineon’s 3.5G physical layer architecture is future proof and designed for an easy upgrade to higher HSDPA data rates, HSUPA and also Rx-diversity.

S-GOLD3H with its ARM 926 CPU, capable of processing speeds of up to 312 MHz, is extending the capabilities of wireless multimedia without the need for a dedicated Application Processor. The powerful multimedia engine integrated with the advanced dual-mode HSDPA/WCDMA/E-GPRS modem technology enables a wide spectrum of multimedia functionalities, mobile entertainment and office applications with high data rates of up to 7.2 Mbit/s.

S-GOLD3H based platforms enable handsets to provide consumer electronic quality such as camera support of up to 5 MPixel as well as video telephony, streaming, recording and playback with up to 30 frames per second and a resolution of up to 320 x 480 pixels (HVGA) in MPEG4, H.264 or Real video formats and advanced audio codecs, like enhanced AAC+.

THE OPTIMIZED S-GOLD3H architecture makes it possible for the users to run several applications simultaneously; e.g. surf the internet, download emails or data to a SD-card with HSDPA category 8 (7.2 Mbit/s) while listening to MP3 music over a stereo Bluetooth headset.

■ Feature upgrade flexibility through optional companion/multimedia chips via standardized interface
■ Support of connectivity modules such as Bluetooth, WLAN, A-GPS, DVB-H, FM Radio, etc.

Infineon’s S-GOLD3H product brief (pdf) is here.

[Thanks to MacDailyNews Reader “Adam W.” for the heads up.]


  1. there’s a mistake in the product brief: it mentions H.263 decoding in the specs, but the text description mentions H.264 movie playback. I think the specs are wrong, and should mention H.264 rather than H.263, since no-one uses H.263 for mainstream videos (H.263 is only used in legacy videoconference solutions), and it makes more sense to decode H.264 for movie playback, especially if Apple is going to use this chip (since all movies from iTunes are in H.264).

  2. This story makes a big leap that the SGOLD3 in the SDK is referring to Infineon’s S-GOLD3H chip platform. After all Apple uses a custom Infineon S-GOLD2 chip platform in the current iPhone. I would even take a educated guess that even if Apple uses the Infineon S-GOLD3H chip platform it will be a custom chip set with a custom feature set and in the end will not be the same silicone that makes up the Infineon S-GOLD3H chip platform.
    Power considerations are going to be king in whatever silicone Apple uses for the next rev. of the iPhone hardware.

  3. Jaakko,

    Just in case you’re being serious, all iPhones already have “GPS” via tower triangulation.
    I use it a LOT, at since it’s coupled with Google maps, it has got me where I’ve needed to be on more than one occasion.

  4. GPS is nice but what I really need is a GoogleMap with 3D locator. After trying to find a little shop that after all was found 2 levels underground amongst 200 similar small shops. Yes, it was nice feeling when after 3 hours of walking I found it, but what a waste of time. The same thing happens more or less every time I go outside, GPS gets you half way there with car but then…

  5. That’s quite a chip. So, does the Infineon chip provide ALL the processing power for the iPhone, or for just those tasks associated with communications. Is there an additional processor used in the iPhone?

  6. I thought the guy who stumbled on the code says it’s “SGOLD3” which is apparently EDGE only. Only the SGOLD3H is 3G. Can anyone verify this before we get all worked up?

    I’d love for this to be true but it’d be really crap if i get my hopes up for nothing.

  7. It would be a stupid thing if Apple indeed updates the chip to mere SGOLD3 chip which only has EDGE …but if you ask me it would have to be SGOLD3H chip…It HAS to be…no point of updating the chip with same features right??
