MarkThatMessage is a helpful tweak to have that fixes Apple faulty little time stamp system. Saying its "faulty" is me being a little sarcastic as it does work. Apple has their own way of timestamping and I'm sure its fine for some, but I've found it extremely annoying that I can't see what time I send an SMS. This tweak will leave a time stamp for every SMS you send and receive so you never get confused or forget. You can find MarkThatMessage in Cydia for $.99.
