    I believe that they are different for different iPhone models (2G, 3G, 3GS)

    We can't post apple copyrighted files (or links to them) here on this forum..
    If you have a mac and a copy of the ipsw then you can decrypt and extract the file from the ipsw yourself.

    Simply use pwnagetool 3.1.4 to make a custom ipsw but don't restore it to your iPhone, then rename the ipsw to .zip and unzip it. There is a 230MB file called in your case 018-6028-014.dmg, mount that disk image and you will find the original unpatched CommCenter in this mounted disk image.
    Please read the stickies & search forum before posting!

    Here are the files needed to be backup from unpatched (as far as I know )

    One thing I'd like to suggest people applying the patch is to get the phone into Airplane Mode.

    This way killing CommCenter is more reliable from my experience at least.

The original mms patch just chooses MuxerApp instead of M68. In other words, it performs initialization pertaining to other kind of hardware. However, there were two concerns: 1. I really don't know what MuxerApp hardware is; 2. there are a few more differences between M68 and MuxerApp init.

    So, yes, trying to minimize side-effects, my patch takes a different approach: it changes MMS disabler into Tethering enabler during M68 init. It should be cleaner, as it uses the routine designed for iPhone 2G.

    I don't really know if battery drain was caused by something MuxerApp init does (or doesn't do). But I am glad my version of the hack fixed your problems -- if that's the case.
    I'm also looking into this battery problem and it's related to Push Notifications. If Push notifications is on and there is a PushApp "registered" with Apple's Push server, then battery gets drainned. It's related to the terrible way Apple's resident push daemon (apsd) works. For Push to work it needs to keep an active connection (either TCP or UDP) to the Push Server and use some for of "keep alive". My guess is that the chosen approach drains the battery.

    On the previous MMS patch, killing the daemon would return battery drainage to normal, so my guess is that the MuxerApp init code does something related to Push that causes it do execute even if the user has not configured Push.

    My observations is based on the fact that turning push notifications on (with a properly activated iPhone or an injected) drains the battery the same way, and that is on either a 3G or 3GS phones, and the decrease ratio is comparable to the one caused by the old MMS patch.

    I also use push notifications since I injected certs in my 2G. I never had a battery drain with push. Yes there is a difference. Without push my battery lasts 3 days, with push 2-2.5 days. Which I think is normal because now I always have a data IP address. (I'm on a EDGE network)

    With the previous MMS patch my battery drained in less then 1 day. With this patch there is no battery drain.

    I've used pwnage 3.1.4 could not deselect icy but everything seemed to go fine. Never asked for the .49 after the .36

    but nothing in settings general network

    then tried blackra1n and appleguru' tether but did not restore my phone to original first.


    Still no tether Orion in settings

    any advise or reasonably sure way to tether a 2G?

    Thanks in advance

    You may be right about MuxerApp. However, I myself am not interested in pursuing MuxerApp analysis, because I don't know what it is. I just know it is not iPhone.

    @PrinceDwi
    Thanks for the feedback. From what I've seen, tethering session usage in realtime is not possible with standard Apple software; maybe you saw that in MyWi screenshots? Also, tethering data in Preferences -> Usage may not be possible at this moment; it is a consequence of the design of my hack. There is little benefit and too much complexity in adding that.

    @ttg
    Yes, you may be right about Airplane Mode, but why? Any problems during patching?

    @aviegas, @kdhoe
    My opinion is that Push will always cause a small battery drain. But when the drain becomes downright pathologic, it has other causes. Stopping Push on a MuxerApp'ed iPhone may seem to fix the problem, but let's not forget that correlation does not imply causation. I would steer away from MuxerApp, because I don't want to find out whether my diesel can also run on petrol.

    I'm doing some investigation and it seems that it may be related to the App using Push. Doing some investigation...

    Just a clarification: MuxerApp does not refer to an iPhone Application. It is a designation for some kind of unknown hardware, different from the iPhone (although it is related to the iPhone in some way). I hope I did not create any confusion about this. I should've called it Muxer.
