Hey guys,
I've been searching for the easiest way to make graphical 2d and 3d games. I researched a few iPhone graphics engines and I wanted to post my findings here, and see what everyone else thought. Basically I've looked really hard at Unity3D and iTorque. I've also glanced at SIO2 and Shiva. Here are my findings (mostly Unity and iTorque stuff). I am almost fully convinced to go with Unity, but feel free to prove me wrong.

Unity
No 2D specific engine / no 2D game builder
Easy to debug on iPhone
No source code. Can't access camera. Fully constrained to the Unity environment. Can't use Objective C
Scripts must be written in Javascript or C# which I don't know (steep learning curve?)
Price: Unity Indie: $199 + iPhone Basic: $399 = $600
There seem to be more games and YouTube videos featuring Unity. Does that mean it's more popular? Easier to use?
$600 version requires Unity splash screen and bigger memory footprint than the expensive version: $3000.

iTorque
3D iPhone engine is still in beta
2D and 3D game engines
Source code included. You can talk to iPhone SDK.
Pain to debug and load on the iPhone (not as easy as unity 1-click)
Price: 2D TGB Pro: $250 + $500 license for the first game. $100 license for the next games. = $750
3D TGE: $150 + $500 license for first game, $100 each additional.
No iPhone Demo

Shiva
Runs on windows only. Not considered

SIO2
Open Source - $0
Doesn't seem to be as full featured as Unity.
