iPhone 4.0.1, iPad 3.2.1 Firmware Released

After yesterdays private release of iOS 4.1 to Apple Developers, Apple has now released iOS 4.0.1 to the general public.

The 4.0.1 update is for iPhone 3G, iPhone 3GS, and iPhone 4. This update includes the new, improved formula for calculating signal strength, though no real change has been observed.


A 3.2.1 update for iPad has also be released fixing Wi-Fi issues among other things:

Fixed an issue that could prevent copy and paste of single-page PDF attachments in Mail
Addressed an issue that could cause video playback to freeze
Improved reliability of video-out when using iPad Dock Connector to VGA Adapter
Added Bing as an option for Safari's search field

Jailbreakers beware, don't update your device until an official jailbreak is out.

iOS 4.1 Beta Released for Developers

The long-awaited update to iOS 4.0 is showing signs that it will soon be released to the public. iOS 4.1 is now available for Registered Developers to download in the Apple Developer Center

The update has been confirmed to fix the reception problems commonly found with the iPhone 4 (and some older devices) when held with a death grip.

The change will adopt a recently recommended formula from AT&T that will more accurately display actual signal strength at any given time. The update will also increase the size of the smaller bars (1, 2, and 3) to make them easier to see.

Though Apple claims that this update should solve reception issues, many are claiming that the issues are much larger than just software - they could be a result of the new antenna design.

If you are jailbroken on iOS 4.0, don't update to 4.1 until an official jailbreak is released.

Update: MobileCrunch has tested the new iOS 4.1 and it in-fact does not fix the iPhone 4's reception issues.

iOS 4 Releases Tomorrow

Tomorrow, June 21, 2010, Apple is releasing iOS 4. The new firmware has over 100 new updates including multitasking, folders (similar to Categories for jailbroken users), better mail, and iBook.

Unlike previous firmware updates, this update is completely free to all iDevice users who have one of the devices that are supported by the update.

The update will support: iPod touch 2nd Generation, iPod touch 3rd Generation, iPhone 3G, iPhone 3GS, and iPhone 4.

Remember if you are currently jailbroken or on an unlocked iPhone, do not update to iOS 4 until a new QuickPWN, Redsn0w or Blackra1n is released. This should be a small wait time (a few days) as the jailbreak developers have already gotten their hands on iOS 4.
