It’s been five days since I got an iPhone 3GS and here are just some quick thoughts.

Things I like:

• The caller photo is BIG.
• The mobile web experience is a whole lot better (I think I’m gonna use way more data that I used to consume with the E71).
• Calendar syncs well with my Google Calendar, which is synced to my iCal.
• Tethering is very simple, both via Bluetooth or USB cable.
• It’s intelligent enough to switch connection modes without configuring anything (Wifi to mobile data). Just switch Wifi off and it will use Cell data automatically.
• It doesn’t have a problem storing numbers with special codes (for VOIP rates).
• Copy/Paste is intuitive. I’ve already used it several times with great success.
• Everything is a whole lot faster compared to my first-gen iPod Touch – Safari and all the other native apps come up instantly, my Twitter apps open faster.

Things I don’t like:

• Mail app could be better. I usually end up using Gmail’s mobile site instead, which just works so well on the iPhone.
• The battery doesn’t last as long as I hoped. But we’ll see how it goes once my usage normalizes.
• No ringer profiles – cause there are times I want the phone to be silent w/vibrate, then silent w/out vibrate, ringer on w/out vibrate and ringer on w/vibrate. Not a major annoyance though.
