CyCorder isn't supported 4.0 on up
Drat!
Since I'm brand new to Apple products, and the vast offerings for them, I'm confused why the Saurik Cydia site doesn't even 'mention' this all-important fact of the iOS support!

3G the best firmware is 3.1.3 here is a good link to get it.
http://www.felixbruns.de/iPod/firmware/ after you install it Cycorder should work fine.
Thanks for that link since all things Apple are new to me - and - to know which is the BEST iOS is a wonderful tidbit of valuable insight.
However, my initial 'goal' is to first try to get the application to work on the existing iOS; and, if that isn't humanly possible, then to get a similar freeware or payware application to take its place - and - only if both those logical attempts fail, to then downgrade the iOS as a solution of last resort (mainly because I have never touched an iOS in my life and this isn't the right time for me and others like me).
In summary, it's disappointing that Cydia doesn't list the support iOS for Cycorder; but I'll keep googling for answers.
Solution Strategy:
1. The original intent was to figure out what was wrong with Cydia (that, doesn't seem likely now)
2. Then, the next goal will be to find a different freeware video recorder that will work on iOS 4.x
3. If that fails, then we can look at payware video recorders (Qik is one that is proposed but it has severe drawbacks)
4. If all that still fails, the only available solution may be to downgrade the operating system (but I sure hope not)
EDIT: So far, from googling, the following 'solutions' have been proposed:
a) Downgrade the iOS from 4.x to 3.x (this would be the solution of last resort)
b) Upgrade to a payware iPhone 3G stand-alone video recorder that works on iOS 4.x
c) Upgrade to a adware/freeware iPhone 3G stand-alone video recorder that works on iOS 4.x
d) Figure out why Cycorder crashes & resolve that issue (doesn't seem likely at this point)
