I'm not sure about your phone, check binaries or route through a PC.
Some parts are encrypted with SSL, for that you need to use a MitM attack (proxy that generates certificates)

Probably. Funnily enough I only have an Android phone.
The easiest way (works from any GSM phone) is to dial *#06#

Generally speaking - yes. There may be exceptions though.

P.S. I get the same code via Voice/SMS etc. It never seems to change.
Perhaps that user had two different SIMs that both used the phone as storage, or WhatsApp changed the algorithm.
I'm pretty sure it's just some sort of checksum. They're probably doing something really simple.

For iphone devices, IMEI is NOT used.

Instead, they take the Unique Identifier value.

You can get this value from iTunes, plug in your device, open itunes, click on the name of your device.
You should see Serial Number, click on it and it will swap to UDID which is the required value.

Your UDID on WhatsApp servers will be md5( reverseOf(UDID) )

That was a problem I had when registering the way I described: The registered Account wasn't found by an official client.
Maybe you need to be logged in to get found?
But great to see that you are now able to make a connection to the server!
I confirm it's for some reason not being found by the official client. Also weirdly after I send the initial presence, the response presence comes with an attribute status="dirty" , not sure what this means.
Code:
<presence status="dirty" xmlns="w" from="s.whatsapp.net">
<category timestamp="1329363611" name="groups">
</category>
</presence>

Just wanted to drop in and say I'm observing this port very closely.
Unfortunately, it is beyond my knowledge to help you at this phase.

I can only offer my time and code skill once you have every http request sorted out.
I can make clients for any wanted Nokia platform and phone. :cool:

Good luck guys! :)

I managed to compile FunXMPP.java in the decompiled version of whatsapp which greatly helped in tracing and understanding the code. I'm creating the app using python and BIG THANKS to the very informative guide posted by ColaCheater. I created the 3 functions concerned with registration (obtaining reg code from server, registering the whatsapp account, and checking account existence). That was easy to implement.

And then moving on to login, things turned out a bit complex, I rewrote the whatsapp login functions in python:

Code:
out.streamStart(connection.domain, connection.resource); sendFeatures();
sendAuth();
in.streamStart();
String challengeData = readFeaturesAndChallenge(); sendResponse(challengeData);
readSuccess();
which is working great and I'm able to login now.

Can I guys work with you, Ive been doing the same thing, although the Ive implemented the man in the middle attack through an actual computer in the middle with a sniffer/forwarder after playing with the DNS records.

Anyways, tgalal, how I can get ur working version so far of the decompiled FunXMPP.java or the python version? Can I talk to you privately?

Attached is a modified WhatsApp 2.0.7 source for S40. I modified it so that I could directly compile FunXMPP (com/whatsapp/client/FunXMPP.java) without problems. I've added a main method to it too that setups a connection and invokes login.(taken from FunXMPPRunner.java). Make sure to change chatUserID in the main method to your phone number.

Thanks for this. Also I wanted to point out that you should use this modified version only to see how login works. Because to make it work I removed some chunks of code that were causing compilation errors and I chose to completely remove them instead of fixing since they weren't used at login (mainly parts related to Iq reqeuests).

I'm guessing you didn't do registration properly, but I'm not really sure.

Also, could it be that the number has been re-used?
Can you check a different number and see the status of that also?

I should have a public registration done within the next few days and if mine doesn't work, I'll have NFI why (I'm emulating the full process)
