Apps can't be updated?

[DylanGSW]

I have an iPod touch 4g and I have bought some apps direct from my iPod's app store. Some games have available updates but unfortunately they cannot be updated. A message comes up saying that I don't have enough memory.. Even though I have about 80 mb of space.
Is this enough.?????
Or is something else the matter?
Please reply

Some apps are larger than 80MB.

Have you looked in the iTunes Store (on your computer) to see what the size of the apps being updated are?

I'll check thanks for the tip..
But I thought that the updates didn't take more memory when they get updated...I thought they woul just take the memory of the previous version.. Anyway thanks for the tip
