What talking you? With wifi, whatsapp still will work and send out messages. Don't believe? Try take out whole sim card, enable wifi, you will still be able to whatsapp.
I think I should rephrase, and just tell the problem directly...
Yes, you're right that in airplane mode + wifi on, whatsapp uses wifi.
The 'problem' comes in when phone is in normal mode + wifi on. Instead of using wifi, whatsapp is using cellular data to send/receive. If I force stay on 2G and wifi on, then whatsapp is using GPRS, and the transmission caused interference noise with my computer speakers. No noise is created when 3G and wifi are on. So I deduce whatsapp is using cellular data over wifi.
Not sure if this is a software bug or what. Don't remember having such phenomenon for 3GS + older version of whatsapp.
