There are a few things you should consider before buying an iPhone now:

1. There is only 1 week's warranty for iPhones purchased in Malaysia.
2. You are being one of the pioneers, thus lacking mature technical support unlike the other conventional PDA phones.
3. There are many limitations in terms of compatibility between iPhone and Windows OS, unless you are using an apple machine.
4. There is a possibility that the 3G version will be announced this year.
5. It's darn expensive. LOL.

Otherwise, iPhone is a great phone to own.
