one of my friend is online all the while, but my sms has not been delivered to him for two days already
is your friend on blackberry? blackberry users are always 'online' on whatsapp. ask your friend to do a battery pull and restart the phone. that will probably work.
my whatsapp is working fine for me leh. push messages everything. it ain't as bad as what people are saying. maybe just one or two incidents where the messages get a little delayed. other than that, its fine. am i lucky? or are people just exaggerating to vent their frustrations? haha. bottom line is, it's not as bad as what people make it out to be. and it's probably one of the best ones around. unlike ping, cheat money one.
