iPod touch How do I know when to stop? (upgrading apps, that is...)

[ukalady]

I think I've made a big mistake in automatically upgrading my apps and the iOS for my 1G (iOS 3.1.3) because I now have apps that no longer work on that generation; they just start up and then shut down. The developer says it's because the upgraded apps no longer work with the 1G devices at 3.1.3--if I'd known that, I'd not have upgraded the app/iOS because I'd rather have an "old" app with fewer features than a non-working app.

Considering that I'm now stuck (am I? I did go back and save the earlier .ipa files from a week-old back up so I *do* have those), how can I best maintain my 1G with the working apps I have now? Do I *never* upgrade apps/iOS on the 1G again? How can I tell before upgrading (short of a warning: "Not for 1G devices")?

And, further, since my new 4G arrives Monday (crossed fingers), how can I have the most current apps for it and still maintain the 1G at a functional state? Can iTunes keep two sets of the same apps (old and new) in one iTunes account or will I have to set up a *new* iTunes account for the new 4G to be able to have the new apps on that one?

Am I missing something here? (Entirely possible--I'm old enough to be a grandma to many of you folks posting here--but I sure appreciate lurking and the info shared!).

Did you sync it with the 'old' apps on?
I find that whenever an app is replaced by a newer one in the itunes library, the old copy gets moved to the trash / recycle, so it may be worth looking in there.

I've had a tendency to keep all my old ones in a folder called 'old apps' just for some such eventuality, although that's growing a little big and unwieldy now...

edit. somehow didn't read.
Yes; just re-use the .ipa for the app / version you want.

If you just drag it to itunes, it seems to create an 'orphaned' duplicate that never gets updated, while the standard does.

I *do* have the old apps' .ipa files, but eliminating them from the iPod as well as iTunes and then dragging the .ipa files back in doesn't seem to change anything. I think it's the most recent upgrade of the iOS that scotched it...
