Just picked up a request from the DEV IDEA POOL

1. Launch app
2. app asks for email address
3. user types in email address or selects email from list of last-used addresses
4. app asks "Are you sure?" with suitable warning
5. app writes selected email address to following regkeys:

[HKCU\Software\Microsoft\ActiveSync\Partners\{B2830118-7BC6-4A74-8C9A-3D8B9CEF88E0}]
"Email"=your_new_id@hotmail.com
"User"=your_new_id@hotmail.com

[HKCU\Software\Microsoft\IdentityCRL\Environment\Production]
"DefaultID"=your_new_id@hotmail.com

6. app automatically reboots phone

Simple enough, right?

Here it is!

Because I made no test on myself please give me feedback if the registry values get applied

ne0cr0n, unfortunately, "my" method has some important cons (you should list 'em) - after that change you'll be not able to upload pictures to SkyDrive, also some accounts like Twitter will be non-functional I've tried to find some workaround but without success...

but you can revert it back, right?

The new LiveID could be associated to a different market zone, which you could use to buy some apps with your correct credit card infos, then revert back to your main LiveID, and regain all regular functionalities like auto uploads to skydrive, twitter integration, etc.

Am I right?

I'm so sorry but I can't confirm - just never tested this way. I've researched that hack 'cause damn Verizon blocked and deleted my very-very old email ( @verizon.net) what I've used during 11 years, and also as my LiveID email.

Wow dude thanks for writing the app so quickly. What is the etiquette for sharing apps? Are you supposed to share source code too? I don't want to be rude by asking you for the source


I don't use twitter, but I was able to upload a photo to skydrive just fine after swapping LiveID's. Steps:

reset my phone with my own liveID
download bunch of apps from appstore
dev unlock/interop, etc
manually edit registry and change to my wife's LiveID (she has zunepass on her ID which is why I wanted to swap to hers)
reboot phone
take picture
upload to skydrive
login to skydrive app and see that picture is there on *my* skydrive account, not my wife's




So skydrive integration with picture hub/camera obviously stored my liveID and credentials somewhere other than the regkeys I edited. Most likely Twitter is the same way.

I presume the credential data is stored encrypted in some weird GUID key with no obvious pattern. Too bad there is no regmon/procmon tool like on Big windows, otherwise I could figure it out in a few seconds... Although somehow I doubt that you can use provxml to import export those keys to re-write encrypted credentials. That would be a pretty bad exploit.

So I ran IDSwitch and it gave me the error "no root access". Hmm. So I went into WP7 Root tools and switched on "trusted" for the app.

So a pre-requisite for running the app is to have WP7 root tools? I'm kinda new at this so perhaps that is an assumption of any app that is going to do interop/native stuff? In order to get it to work you have to set it to "trusted"?

Anyway the app let me type in the new liveID and rebooted the phone, but upon booting up, it appears that the old LiveID is still there in the 3 registry settings. I ran it a second time and the app remembered the address I typed in so thats cool. BUt again after rebooting, it failed to modify the registry entries.

Can you post up a debug version with some breakpoints or console spew? I could try to attach a debugger on my end (not sure I know how to do that, but I can try to figure it out)

Thanks for the info. I will add a warning and how to use message when launching the app for the first time.

I will do that, but the code is kind of ugly xD

I uploaded the source. Should make things much easier

I tried it on Samsung Focus Mango updated with WP7 Root Tools. Even though it reboots but it does not change the primary id. After reboot when I open the app again, it shows the primary id as the old id and not the id to which I wanted to switch.

Found the bug. I used the content from to current ID textbox not the new ID textbox -.-
