iPhone iOS4 Connectivity Profiles Is there any way to set up and easily switch connection profiles in iOS4?

i.e:

Home - Wi-Fi on, Bluetooth off, 3G off

Work - Wi-Fi off, Bluetooth off, 3G off

Car - Wi-Fi off, Bluetooth on, 3G on

etc.

Would prefer an App Store app but would consider a jailbreak app if not available.
If your phone is jailbroken, SBSettings works really well for this. I don't think it supports profiles, but it gives quick access to toggles for all of the services you mentioned. Very helpful for the scenarios you described.
