Chrisma: /* Bluetooth Chip */

[[Image:IPhone3G.png|right|thumb|iPhone 3G]]

This is the iPhone 3G. It was released on July 11, 2008. Features the inclusion of 3G networking and GPS, along with a tapered plastic back in black and white colors (8 GB model not available in white).

==Internals==
''See: [[N82ap (Internals)]]''

== GPS ==
Unlike the [[M68ap|previous model]], iPhone 3G has GPS capabilities, powered by the [[Infineon PMB2525|Infineon Hammerhead II PMB2525]] GPS chip

== Baseband ==
The iPhone 3G uses the [[X-Gold 608]] baseband chip

== Application Processor ==
It makes use of the [[S5L8900]] application processor. At the time, the [[M68ap|iPhone]], iPhone 3G, and [[N45ap|iPod touch]] all use this same processor.

== WLAN and Bluetooth Chip ==
The iPhone 3G uses a different chip than the iPhone 2G. It uses a Marvell [http://www.marvell.com/wireless/assets/8686.pdf] 88x8686. The firmware files "helper_sd.bin" and "sd8686.bin" can be downloaded from the Marvell support section, there are included in the "Linux 2.6 Fedora" package - they are needed for iDroid installation. The chip supports [[Bluetooth]] 2.1+EDR and all available profiles. The iPhone OS only supports Bluetooth 2.0 and limited profiles for this device. The chip is the CSR BlueCore6-ROM.

== Specifications ==
* '''Color''': Black (8 GB or 16 GB) or white (16 GB)
* '''Size''': 4.5 inches (115.5 mm) (h) × 2.4 inches (62.1 mm) (w) × 0.48 inch (12.3 mm) (d)
* '''Weight''': 133 g (4.7 oz)
* Headphone jack (non-recessed)
* '''Battery''' has up to 10 hours of 2G talk, 5 hours of 3G talk, 5 (3G) or 6 (Wi-Fi) hours of Internet use, 7 hours of video playback, and up to 24 hours of audio playback, lasting over 300 hours on standby.
* '''3G''' for broadband data speeds (Tri band UMTS / HSDPA: UMTS 850 / 1900 / 2100)
* Assisted GPS, with preference to location based on Wi-Fi or cell towers
* Digital SAR Rating: 1.38 W/kg

==iOS 4==
iOS 4 runs on the iPhone 3G, but for sake of performance, the in-built wallpapers and multitasking features are disabled (though these are easy to re-enable using [[redsn0w]]). Using Veency and measuring the delay of wallpaper and no-wallpaper on the same device while recording computer screen and measures around 100ms delay for the wallpaper. The iPhone 3G also misses out on various other features, including Game Center, orientation lock and other features the [[iPhone 3GS]] introduced with iOS 3, such as Voice Control and video recording.

location services are a set of different methods to determine the current location of a devices (and its user).
This location data might be stored in pictures taken or used for navigation.
The available methods vary on device type.

== WLAN ==

Signatures (SSIDs) of WLANs in the current location are polled and send to a database which has also the
location information of all known WLANs. Such database services are provided by Google and skyhookwireless. Apple claims that they are
not using these services since IOS 3.2 - and provide a similar service themselves. An active Internet connection
is required to send singatures to the database and get location coordinates in return.
This is the only method used for ipod touch devices.

== A-GPS (Assisted GPS) ==

This method uses GSM/UTMS protocols to quickly identify the approximate current location. The GSM/UMTS network is organized in cells and from currently subscribed cell ID it is possible to get a first guestimate on the current location.
If neighbourhood cells can be taken into account as well a more precise location estimation might be possible. In addition
these direct location information network operators may also provide so-called almanach data for faster satellite GPS synchronisation. Read more details here: [[http://en.wikipedia.org/wiki/Assisted_GPS|Assisted_GPS]].

However, none of these services are mandatory standards. If provided, network operators usually charge
for these services and this is one of the reasons why costs are generated even without initiated phone calls.
Another disadvantage is that reponse is rather inaccurate, at least insufficient for navigation purposes.
Avantages are fast response and coverage in buildings.

== GPS (satellite) ==

Satellite [[http://en.wikipedia.org/wiki/Global_positioning_system|GPS]] GPS is the most accurate method and hence suitable for even navigation purposes. On the other hand it may take up to 10minutes to "fix" and will most likely work only outdoors. In idevices various (different) chipsets are used for GPS but they have all in common that these are controlled by the baseband firmware. So idevices without bandbase don't have GPS, too.

== ipadBB 6.15.00 losing GPS function ==

If an ipad baseband [[6.15.00]] is installed on iphone 3G or 3GS it is resulting in loss of (satellite) GPS functionality.
Reason is that for GSM/UMTS radio function ipad1 and iphone 3G or 3GS using the same GSM/UTMS chipset [[X-Gold 608]] but different
GPS chips: [[BCM4750]] in ipad1 while [[Infineon_PMB2525]] in iphone 3G and 3GS. So the ipad
baseband is (assumingly) not containing a device driver for the Infineon PMB2525 and hence this CPS chip cannot be used.
As [[Baseband]] is totally separated from rest of the iphone logic - only communicating over a serial link - there is
no alternative way to address the unused GPS chip. Meanwhile all hopes have been burried of a downgrade option for
ipad baseband. So if for unlocking a vulnerable baseband firmware is needed always check if an older version of iOS
is installed or can be restored (if SHSH blobs are available) and then using snowbreeze for iOS upgrade without
baseband upgrade. Only if this is no option consider installing ipad baseband.
