I was looking around for a Phone for some time since a couple of months ago. My main criteria was that the phone must allow me to enter data fairly quickly and have a large enough screen for surfing the net, so I narrowed it down to the Nokia N97 because it has an external keyboard.

In the end, curiosity about the new iPhone 3GS got the better of me, and now I am the owner of a 32GB 3GS ... and a SingTel contract.

I've been using the 3GS for nearly a month now. My phone is not "jailbroken" and is currently running on OS 3.1. This is what I think:

Likes:
- fast and smooth user friendly interface
- a whole lot of applications available
- Huge built-in memory for all kinds of stuff
- keyboard in landscape mode works better than a physical one (I can type almost as fast as if I am on a full sized keyboard now!)
- Location based services aplenty, and current location is determined quite accurately
- many accessories in the market

Dislikes:
- iTunes not exactly very zippy or user friendly. Not used to their "sync" concept.
- Battery power lasts about a day (less if you use Wifi and 3G data)
- Proprietary OS imposes restrictions on developer's apps (e.g. developer's applications are single threaded and not multi-threaded) I used to have a timer application running on my Nokia to remind me when to put my eyedrops. The iPhone has a similar app but requires it to run in the foreground. If you close it, it doesn't work anymore.
- A number of restrictions on the OS, most noticeable is the lack of Bluetooth file transfer (i.e. I cannot send files or pictures to someone else using Bluetooth)
- You cannot replace the built-in Calendar application with a better third party application
- There is no TASKS and TODO lists available on the iPhone
- The battery is part of the phone and not user replaceable.

I'm sure there's more but these are just the main ones which I can think about right now. Overall it is a good phone, but does it live up to it's hype? Well almost ...
