Seeking Better Mobile Solution

So, I love my iPhone. There are some things that it can’t do that I really really want.

1. 3G Data Speeds… EDGE is too damn slow.
2. Video Broadcasting … no app exists, and it would be too slow anyway.
3. GPS. Location-based notifications among other things, also broadcasting my location. Also, tracking my whereabouts for posterity.
4. Ability to act as WiFi hotspot. I want to share that 3G speed to my laptop… or to yours, wherever we go.

These things -might- get updated this summer with the next iPhone, but I doubt we’ll see video broadcasting or real GPS. And frankly, I don’t really want to buy another iPhone. And I also don’t want to wait that long.

So I’m thinking about getting a Nokia N95, or something comparable. There are applications to do all of the aforementioned things. And, I could still use my iPhone to browse the web over the WiFi connection the Nokia creates. One cool thing is that I can just pop the SIM card out of my iPhone and into the Nokia, keeping the same phone number… and my unlimited data plan from AT&T includes 3G already so it won’t cost me any more per month.

The only thing is, I don’t know if it will work the way I want, or if I’ll be happy with the phone itself. Know of a better solution?
