Upgrading from 3.1.3 on a 3g 32gb iPod

[Spyker8]

I haven't really been up to date on how jailbreaking works ever since Spirit came out for 3.1.3. I was considering updating to iOS4 but not sure if I should. Is there any major reasons why I shouldn't upgrade from 3.1.3 to iOS4? Is there anything I can do better/easier on 3.1.3 that I can't on iOS4?

You should be fine to update. It will add quite a few features. If you plan on jailbreaking you should stick to 4.1 (as long as you have SHSH) otherwise your jailbreak will be tethered on 4.2.1

Thanks for the info and the quick reply! I shall go ahead and upgrade to 4.1, as I do have my SHSH saved.
