Updating 4 2 version on iphone 3gs
June 2007 saw the official release of what eventually became i OS – concurrently with the first i Phone.i OS did not have an official name until the official release of the i Phone software development kit (i Phone SDK) on March 6, 2008.And that version was not compatible with my then Tiger OSX.So, today I had my OSX upgraded from 10.4.11 to 10.5, and i Tunes upgraded from 9.2.1 to 10.6.The other was i OS 4.2, replaced with 4.2.1 due to a Wi-Fi bug in 4.2 beta 3, causing Apple to release 2 golden masters (4.2 GM and 4.2.1 GM).Apple announced i Phone OS 1 at the i Phone keynote on January 9, 2007, and it was released to the public alongside the original i Phone on June 29, 2007.No official name was given on its initial release; Apple marketing literature simply stated the i Phone runs a version of Apple's desktop operating system, OS X.Apple announced i Phone OS 2 at the i Phone software roadmap keynote in March 2008, and it was released to the public on July 11, 2008 alongside the i Phone 3G.
I'm given the impression that the only way this can happen is if I unlock the phone. I haven't heard about Apple putting such a lock into i Tunes, but I suppose it's possible. If you choose to "unlock" your phone as you put it, then don't come back here for help.seems pointless and a waste of time, but hey it's your time I guess. My Mac Book Pro runs on Leopard 10.5; my i Tunes is version 10.6.i Phone OS 3 was compatible with all devices released up to that time, but not all features were available on the original i Phone.
The final release supported on the original i Phone and i Pod Touch (1st generation) was i Phone OS 3.1.3.i Phone users receive all software updates for free, while i Pod Touch users paid for the 2.0 and 3.0 major software updates.As of i OS 4, Apple no longer charges money for i Pod Touch updates. i Phone OS 1.2, which after the first beta was replaced by a 2.0 version number; the second beta was named 2.0 beta 2 instead of 1.2 beta 2.Before then, Apple marketing simply stated that i Phone ran a version of Mac OS X made specifically for i Phone. It was officially renamed i OS on June 7, 2010 with the announcement and introduction of i Pad.
