    If you install iOS 4 and jailbreak,

    1) Do you lose features like visual voicemail and MMS?

    2) Can you remove/uninstall the jailbreak after editing the plist file and keep multitasking and wallpapers?

    3) Do apps look at your iphone model to see whether it is a 3GS and will it lock out multitasking? For example, skype hi-def audio works only on the 3GS so they may block out multitasking on the 3g even though it's unlocked with a jailbreak.

    4) If you single click the home button while running an app, does it close the app or just keep it multitasking?

    5) How well does the iphone 3g run with only 2 tasks multitasked, for example safari and skype.

    Thanks.

    There was a thread around here that the OP ended going back because multi task and what not was not great on 3 G

    1. You shouldn't lose any.

    2. No.

    3. Skype needs to be updated first to allow multitasking, then we will see. It's unlikely skype will bother to check.

    4. Close the app and keep a saved state (at least it suppose to do that). Voip apps will remain in background.

    5. See 3.

    Hope it helps

    No apps go to the background or save state yet. They all have to be recompiled for 4.0 to take advantage of that. Every app you currently have will quit on exit.

    And apps can check in code for a specific model device and prevent features from working. The plist hack won't get around that.

    1st-party/native apps like Mail, Safari, Settings, App Store, Clock, Calendar, Maps, etc. all have the new multi-tasking/save-state routines built in, so you could try some of those on the 3G and see how it runs.

    Thanks for all the responses. It seems that the multitasking hack might work for some programs but not others. We'll have to see how developers handle the code.
