n900 doesnt have a big fan base for whatsapp although this thread took some fame. lets say 10,000 users, not enough to make a invest on a dieing operating system.

@Scorpius I currently have a working yappari, in case i flash the device how I can keep it working without registering n900 with whatsapp server. My second question is, is it safe to synchronize my contacts every now and then or will it block my account due to buggy synchronization?
