What does it do? Not much according to ZDNet's Adrian Kingsley-Hughes. The release notes say that it "Improves the formula to determine how many bars of signal strength to display."
I hope that the update addresses more than that. What about the proximity sensor and Bluetooth bugs? We'll have a bit until everyone gets a chance to test it.
iOS 4.0.1 is compatible with iPhone 3G, 3GS and 4 and is available by connecting your iPhone to iTunes and clicking on "check for updates."
Update: Apple also pushed out iOS 3.5.1 for iPad WiFi and 3G iPad models which does slightly more than change the display of the signal bar. According to the release notes:
- Improved Wi-Fi connectivity
- 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
