iPhone and iPad owners will find themselves with an update ready to download and install from Apple, containing a number of minor bug fixes.
iOS 4.0.1 for iPhone "improves the formula to determine how many bars of signal strength to display". Apple had stated previously that reception issues were not exclusive to iPhone 4, and that there was in fact a calculation error in the formula used to calculate how much reception an iPhone has at any given time. In addition, Apple has enlarged the size of the first two reception bars at the top left hand of the screen, making it easier for users to distinguish how many bars of reception their iPhone currently has. The update is 305.5MB.
We have discovered the cause of this dramatic drop in bars, and it is both simple and surprising.
Upon investigation, we were stunned to find that the formula we use to calculate how many bars of signal strength to display is totally wrong. Our formula, in many instances, mistakenly displays 2 more bars than it should for a given signal strength.
The reception issues on our iPhone 4 remain unresolved. Apple have called a conference tomorrow to speak to the press about the reception issue. Rumours of a total recall and Apple offering a free bumper-case are just some of the ideas floating around at the minute - all will be confirmed tomorrow.
iOS 3.2.1 for iPad sees a number of fixes, most notably improved Wi-Fi connectivity for users that reported frequent dropped connections. In addition, the update "fixes an issue that could prevent copy and paste of single-page PDF attachments in Mail". The other minor fixes are: "addressed an issue that could cause video playback to freeze", "improved reliability of video-out when using iPad Dock Connector to VGA Adapter" and "added Bing as an option for Safari's search field". The update is approximately 450MB.
The updates are free, and can be downloaded and installed through iTunes whenever you plug your device in.
