For delaying the animation, you are given an option to alter the delay or duration of your Animation entirely or individually. To do so you need to use the Activatior in order to select the activation method.
And each time you change in the settings of iLettras, then you are required to invoke the activation method in order to apply the changes.

Currently the iLettars's price is $1.59, available in Cydia under the ModMyi repository.
