Apple hasn't released a time when the update will become available today, however if history is any indicator, it's likely the update will be offered to users beginning around 1 p.m. ET.
The iOS 8.1 update is also expected to address a number of lingering bug fixes from previous iterations of the operating system, which was released last month.
Here's what you can expect from iOS 8.1.
Apple's mobile payment product, which works on the iPhone 6 and iPhone 6 Plus for online as well as brick and mortar store purchases, is perhaps the most anticipated update to come from iOS 8.1.
It's now even easier for your Apple devices to be "friends" with each other.
The new iOS 8.1 comes with more continuity features that allow users to seamlessly transition between OS X Yosemite and iOS, including the ability to send and receive text messages from iPads and Macs. The feature even works for contacts who don't have an iPhone, making it even easier to stay in touch on any device.
Forget about paying for Wi-Fi, too. An iOS 8.1 update allows Mac users who have certain carriers to connect to the Internet on their computers -- using their iPhone as a Wi-Fi hot spot.
Good news -- the camera roll that was stripped from iOS 8 is back. Also expect to see an iCloud photo library that lets you store photos and videos to your iCloud and makes them even easier to find.
The library will come with the ability to search by date, location or album name.
