T3.co.uk claims to have seen a forthcoming update to the iPhone -- firmware version 1.1.2. According to T3:
First off, there's support for dozens of languages, so if you happen to be a fluent Cantonese speaker, the phone has all the relevant character sets so you can display your language properly.
There's full support for French and German, with special keyboard lay-outs on the ready to tackle accented characters - perfectly understandable, of course, what with the phone heading for launch across the channel this month too.
MacRumors had also independently heard that iPhone Firmware 1.1.2 is destined to arrive upon the European launch of the iPhone later this week. According to these sources, the release will be mainly bug and security related with some European language localizations, and will require yet-unreleased iTunes 7.5 to sync.
Our source also mentioned that 3rd party SIM unlock software will be once again broken as well as some 3rd party applications. iToner was specifically mentioned as being broken by the update, though readers should note that Ambrosia has released a free update for every firmware release thus-far.
Readers may remember that the iPhone 1.1.1 update disabled all native 3rd party applications and even "bricked" some iPhones that had undergone certain SIM unlocks, which lead to a somewhat rough public reaction and aftermath. Nevertheless, workarounds were discovered and methods have once again been developed to jailbreak the iPhone in one step.
