The dealbreakers for me:
- Cingular. They're good, but it would be so much better if Apple sold all iPhones unlocked.
- No 3G. Sure, it's fast, but you would think that a cutting-edge phone has cutting-edge speed.
- 4GB & 8GB. Until it reaches 30GB minimum, no go for me.
- Built-in battery. Still the same old tradition of non-removable batteries. Sure, it looks 'clean', but I would rather have functionality over that.
