The recently released iPhone SDK Beta 3 continues to give up juicy hints as to Apple’s intents for the handset’s next major update; not only has the 3G chipset been identified but new code referring to stereo Bluetooth headset support, suggestions of GPS and new functionality for mobile Safari and Google Maps. There are also signs that Apple may not be taking the ongoing hacking of the iPhone lying down, with the inclusion of a “BRICKED_AND_LOCKED_SIM_STRING” that suggests the handset could seize up should an unlocking attempt be made.
In terms of Bluetooth, A2DP has been included in the code as well as “HeadphonesBT” that indicates wireless stereo capabilities, long requested for the handset. Bluetooth remote control is also mentioned. The new beta also references “RoleGPS”, which many have assumed will mean either in-built navigation capabilities or at least compatibility with an external GPS device (likely connected via Bluetooth).
The library also includes a mention of “Printers”, a new addition, while reference to Nike+ sports monitoring equipment have been deleted. The suspected integration of the currently standalone YouTube app into mobile Safari is also present, via a “YouTubePlugIn.webplugin” component, and “Google411″ – the search company’s directory enquiry service – is now associated with Google Maps on the iPhone.
Finally, there are suspicions that Apple will require official activation of an iPhone via iTunes before Firmware 2.0 is permitted to install.
