    Just a quick question on multitasking for those of you running ios4 already.

    Lets say I have 2 news apps, both multitasking enabled for ios4.
    If i load one up, then another one up straight after will the first app i loaded continue to download the news whilst I browse on the 2nd app? Or does multitasking just "freeze" the state of the first app until I go back to it?

    At the moment I'm jailbroken on 3.1.2 and use backgrounder to do this, but just want to know how the new multitasking functions.

    Depends on what the programmer wanted.
    Prior to iOS4 apps had to promptly quit as soon as the quit button is pressed. They had a short time to close down. If they did not comply they were shut down by the OS.

    In OS4 apps can ask for the deadline to be extended. And can remain active for a much longer period.
