Here are your Apple rumors and AAPL news items for today:

iMac: A new rumor claims that Apple (AAPL) is preparing to launch a new iMac this fall, reports AppleInisder. According to the rumors, the new iMac will have a 5K Retina display. This would make it the first of the iMac line to receive the Retina treatment. The new iMac is also rumored to have a 27-inch display. Earlier rumors that the new iMac would include a Retina display were based on a string of code found inside a beta version of OS X Yosemite. This code included a listed resolution of 6,400 by 3,600 pixels.

Watch: Apple may be planning to include more sensors in newer versions of its Apple Watch, MacRumors notes. The Watch includes an accelerometer and a heart-rate sensor. However, earlier rumors surrounding the device claimed that it had more than 10 sensors that could be used to track the wearer’s health. Two sources close to the matter claim that the tech company will include more sensors and better health features in later versions of the wearable technology.

Wi-Fi: AT&T (T) has announced that it plans to offer Wi-Fi calling for the iPhone 6 and 6 Plus in 2015, reports BGR.
