As you are aware that Apple WWDC is planned for tomorrow i.e. 8-June-2015 in which it is assumed that iOS 8.4 is also part of agenda, but 9to5Mac has reported that iOS 8.4 will be released in late June and not at WWDC as it is previously planned.
Apple had originally planned to release iOS 8.4 following the WWDC Keynote on June 8th, but we’ve heard that it’s currently planning to release it during the last week of June. As we also first reported, the new services will be available as a new app on Android for non-iPhones. The new services will likely also be available on the new Apple TV. Apple is not yet readying a version of the new services for other platforms, like Windows Phone, due to their low marketshare.
This time jailbreak community is also waiting for the release of iOS 8.4 software because a recent demonstration of iOS 8.3 Jailbreak has raised the hope for next jailbreak from Pangu.
