Kairos is a new jailbreak tweak that allows you to delay ssending iPhone messages, the jailbreak scene has predictably filled the void by spawning more than a few tweaks that are capable of taking a message and then sending it at a predefined date and time. Some of them are good, some of them are bad, but a new entry into the field is both good and interesting for a couple of reasons, and it’s available to download from Cydia right now.
The tweak is built completely into the stock Messages app without any app icons added to the Home screen. To schedule a message, simply compose a message within a new or existing thread, hold down on the Send button, and select the Schedule from the tiny context menu that pops up. Set a date and time of choice for your message and hit Select to schedule it.
As you can see, the scheduled messages interface lets you see whether the message is an iMessage or SMS message by showing either a blue or green tab marker to the left of the message. It also shows a preview of the message, the recipient’s name, and the time it will be sent.
Kairos tweak able to turn off Airplane Mode if it is enabled. When a message is due to be sent, Kairos will disable Airplane Mode, send its message, and then re-enable the same mode afterwards.
Kairos tweak can be downloaded for $0.99 from the BigBoss repository right now. After installation, it will add a preferences pane to the Settings app where you can configure a few options.
