A future Cydia tweak will allow us to set reminders to respond to messages received on our iDevices

  iDevices lack many of the basic features of many mobile phones, and Apple has often been heavily criticized for this. Although possible future tweak which I will talk about now is not a basic function of iDevices, it is extremely useful and should be implemented natively in iOS. This tweak could allow us in the future to set reminders to remind us to respond to messages received in the Messages application, the Reminders application being used for this process.

  All we will have to do is to hold down above a message bubble, choose the Remind option, choose the period of time after which we want to be reminded to answer, and that's all. Joshua Tucker announced this concept, he says he's working on a possible tweak and I'm sure we'll see it in Cydia.
