Reverse engineering "WhatsApp"
WhatsApp is a popular IM service based on the phone numbers in your contacts database. The developers have no interest in Maemo or MeeGo, but efforts have been gaining pace to reverse engineer it. Talk user "ColaCheater" has provided some initial in-depth documentation: A few weeks ago I also tried to look a little bit into WhatsApp but had to give up because of my final exams at school. I used the Symbian S40 Client and decompiled the .jar you can find via google to look a little bit into it. I'm not a programmer but had done some "Hello World" stuff on Java before so I tried to understand a little bit what is going on in the Client. (In the following work I always pretended to be an Nokia C3-00 just that you know when it appears i.e. in the User-Agent)
