Isn't competition a wonderful thing?
Don't worry, Apple will have to give in to multitasking and Flash too if they expect to keep up with WM and Android devices. The cult mentality can only carry Apple just so far.
Even then I'll keep my jailbreak for this reason.
As far as backrounding goes, I just want the ability to keep one program of my choice running while using another.
Such as listening to Slacker or SiriusXM while checking my email.
I'd be surprised if they ever enable backgrounding on the older iphones with that memory limitation. The newer 3GS has 256MB of RAM, and has more potential. Perhaps they'll enable it on the 3GS in a future update?
