Thanks. I finally was able to get the tethering option on my 2G. I am having an interesting problem though. Everytime I connect my phone by USB to use the tether, the tether optionon the phone goes vanishes and the 1023 setsback to 1020. I have to set the state back to 1023 and restart my phone and then the option is back.

Has anyone had any luck using bluetooth?

You might also need to add MMS settings to your carriers IPCC profile. As it's known that when editing APN settings removes the MMS settings even on 3G phones.

Hi guys,

First of all: good work. You found out quite a few interesting things. I recommend looking at misd with IDA Pro. I just saw quite a few things that could be patched out... As I'm soon going to switch to a 3gs, I don't want to sacrifice the time for patching misd, but maybe someone else might do that... In the meantime I'll continue to use PdaNet, as I did up to now. Anyway, I think it's possible to patch out the restrictions, but it will definitely take some hours of browsing and understanding code in IDA

Good luck
Rainer

How about setting permissions of that plist to 0444 so that it does not get modified?

Also you could try using "strings" command in Terminal on /usr/libexec/misd to learn what's it about.

Can someone with a 3G/3GS post the contents of the following file:
/var/mobile/Library/Preferences/com.apple.MobileBluetooth.services

Here is what the 2G shows:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

<key>State</key>
<true/>
</dict>
<key>PhonebookService</key>
<dict>
<key>State</key>
<true/>
</dict>
</dict>
</plist>

I think we are missing some networking lines...

This is well beyond my capabilities....anyone else?

This might be a shot in the dark, but what if someone we to load a "enable tethering" profile into the phone and then looked into the files then? Im sure there would be some differences with the files, and all we would have to do is just modify the certain files and they should stay switched when you plug the usb cable from the phone into the computer?

I was able to download another "custom" set of profiles into my phone for the tethering. But I broke down the custom file to see what type of coding it is for sure. I found it here: var/mobile/library/configuration profiles

Code:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

Yes, I saw it if i rebooted the phone after changing it to 1023 and then trying to enable tethering. I think at this point it tries to start the service and fails. Enable syslog and look at the logs.

As I said earlier, it'd be useful to have an idea of how its supposed to work (ie. someone with a working tethering in 3g).

at first, please forgive me my bad english:-/

i enabled the toggle with setting the plist entry to 1023
and enabled syslog on the iphone.

it's quite interessting to see that the dhcpserver is starting and everything needed to patch the connection trough. i left bluetooth off and only tried it via usb and the toogle was gone with starting systempreferences on my mac...


By looking at the launchparameter for the misd-daemon, i found, that the option "-d" is set. on a 3g-iphone its the same.
maybe there is a launch option that enables the sharing via edge/gprs or misd needs to be patched. my thoughts are that we dont need to search for a plist with a missing setting because the daemon is starting and i haven't found a difference between the iphone3g and the iphone2g pref-files at a first look through.

this seems to be the interesting part in the log
(@fgsch i know you have posted already parts of it, but as far as i can see there are more interessting things:-)):
