Hi all ,
I would like to port whatsapp to n900 , i am an experienced programmer but i have no clue on how to build stuff for the n900 .

so anyone who knows how , instead of leaving me looking for some answers please if you know the answer to the following questions please do answer :

1 - any links/stuff on how to build plugins like the google talk/skype/facebook chat
2 - any information about whatsapp protocol (will do ARP and MITM anyway)
3 - anyone have any phone with whatsapp installed and would like to help ?

Edit :
Found something that might help with ARP & MITM attacks :

+ a java programmer needed for couple of questions
please visit this post

I just sent them an email, asking for a port, especially since they already support Symbian. How many people have actually tried that, do we know?

You could decompile the s40 version to see the whatsapp code

Uhhh, screw that?

Unless you're in a country where the laws are abysmally bad, that shouldn't be an issue. In the USA, at least, it's a legal right to reverse engineer for compatibility purposes. Making a compatibility program/plugin for an unsupported platform sounds valid enough to me.

Legalities are a bit trickier if you publish the reverse engineered results in open-source program form, but my unprofessional opinion is that you're still legally in the right to do it... In the event that they decide to be a-holes and try to sue over that, you may well be able to enlist the help of the EFF (Electronic Frontier Foundation), who I believe volunteer their lawyers towards cases of significance towards protecting digital freedoms.
