iOS 4.3.1 on the way, dealing death and destruction to iPad 2 jailbreak

Pleased with the zippy performance of your iPhone, iPod touch or iPad on Apple's new iOS 4.3 software? Join the club. But it seems a few minor gremlins crept into the software update, which may lead Apple to roll out iOS 4.3.1 within the next two weeks.

Boy Genius Report claims to have the details, suggesting a timeframe of "one or two weeks" for the update. There are no major (or indeed minor) new features in the site's list of what will be contained in the update:

• Baseband updates for the iPhone 3GS and iPad
• Fixed memory hang that results in memory corruption when reading large files from USIM filesystem
• Fixed problem with NTLM authentication in apps and on websites
• Fixed issue with the Springboard and third-party apps not recognising the gyroscope on the iPad 2
• Fixed iPad 2 jailbreak vulnerability

That last point is quite significant, of course, squashing the first loophole for would-be jailbreakers to unlock their new tablet. Given it was discovered within a day or two of the iPad 2's launch, we dare say it'll be a similarly short wait after iOS 4.3.1 goes live before someone cracks that too.

That one to two week wait for the update may tie in with previous rumours of an iOS-focused Apple event in early April, to unveil iOS 5 to the world. Apple doesn't need to wait to push out iOS 4.3.1, but it may make neat timing.

The iPhone 5 seems to be taking priority over iOS 5 in the online speculation stakes, but we've already had our guess at what the next big software update may contain: an improved Game Center and AirPrint, the ability to sync with multiple computers, wireless syncing, Flash support and FM radio, among other features. Okay, not Flash support.

For now, we'll have to breathlessly anticipate uncorrupted memory and smooth NTLM authentication as a short-term measure, instead.
