However, WhatsApp seemingly does not support quite a number of countries, but there is a legitimate way around it. Their website quotes in their FAQ:

What countries do you support?

Most of them! We took extra steps during development to make sure WhatsApp works for almost every country in the world and even among contacts in different countries. However, WhatsApp is currently not supported in Malaysia, India, Indonesia, and Thailand

Step-by-step tutorial on getting WhatsApp working

1. Install WhatsApp from the iTunes Store.

2. Before you launch it, go to Settings, then go to the Phone section.

3. Click on My Number.

4. Key in your number preceded with the + symbol and click Save.

5. Now, launch WhatsApp, and if you haven’t ever launched it before, you will be asked whether or not to allow WhatsApp to send you push notifications. Click OK (or else your functionality will be severely limited. If you previously clicked Don’t Allow, you can go back to Settings to modify it under the Notifications section).

6. You will be asked to key in your phone number again.

7. Do so, and click Done. And now you’re really done! WhatsApp should be enabled for you. (Do leave me a comment if this worked for you – it helps my head grow bigger).

For the iPhone 3Gs, I did use the tap-to-focus on the subject feature. All photos are not touched up, and are saved at the highest quality after adding the watermark in Photoshop.

Initial observations are that the tap-to-focus on the iPhone 3Gs also is for metering, and in certain cases, can over or underexpose images depending on where you tap. Overall, the images from the iPhone 3G pale in comparison, as the iPhone 3Gs adds vibrance and a certain warmth to the images. Gone too is the milky film that overlays the iPhone 3G images.
