Am I good on 3.1.3?

[Dawkins Bull-Terrier]

So I'm still on 3.1.3 jb with spirit and not
plannin on goin up to ios4 any time soon. I use Around 40 cydia apps daily and not all ate compatible I'm guessing. I can't get a few apps Like iBooks and
iMovie which look good but hey. I've got
multitasking with backgrounder, folders with categories and irealsms is just amazin. How long can I stay on 3.1.3 before it becomes necesary to update? And am I missing anything else buy not going with ios4? Thanks guys
