obviously u would only use whatsapp if u have a data plan..

if not it's gonna cost u a fortune...

It's an one off payment of 99cents, don't worry..

somehow after the new update, my whatsapp is a bit lagging

broadcast a message for them to update

It would charge when it pushes a message into ur phone.. but then if you turn ON ur data, all your other applications will 'eat' the data as well.. Hence u would have really high charges..

no need add frens, they automatically appear in ur list if they use whatsapp and if u have their number

Haha means he got ur number but u dun have his?

The way whatsapp work is it detects your contact lists based on your phonebook, so as long as you sync'ed ur phonebook with your new iPhone 4. your contacts will be there..

Switching to iPhone4, you have buy the app for a one-off payment of 99cents, and yes you have to activate again and register ur number with it when you first open it in iPhone... No worries, as long as it's the same phone, no matter what sim card you change, it would still work the same as it will still use ur maxis number u registered... i.e. Ppl with ur maxis number will be able to see u in their contact list..

You can register with this overseas sim, BUT the downside is your friends won't know who you are unless you tell them.. You can still text them cause they're on ur contact list..

Same sim on 2 devices, I am not very sure to be honest.. I think it's possible.. Personally I have tried registering the same number on the same blackberry twice cause I had to reinstall whatsapp when I upgraded my Bold to OS6

Hello all!! It's been 3 years sharp since I started this thread, back then whatsapp was not even popular yet! It's great to see how this thread is still being so active although I have not come back to check it. In fact I am not even active in this forum anymore as I was busy with my studies and job hunting in the UK.

Anyways, my post has long been outdated, do PM me if anyone has any suggestions to add in for the 1st post! Happy whatsapping everyone =))!!
