Mobile phones/Cell phones.

I'm currently trying to find a good price plan and contract for a new phone - I'm due to upgrade mine (have been for ages) but haven't found one I like.

But it strikes me, as I wander around the internet, that the UK mobile market and the US one are wildly different. What do you guys in the states/Canada expect from a phone nowadays? Why do phone companies produce different models on each side of the pond?

For a cheap tariff like mine (£15 per month - 300 any network minutes or texts, 300 same network minutes, free email with Google and free Googlemaps) I currently have an LG Viewty - 3" touchscreen, haptic feedback, HDSPA internet, 5mp camera and video recording with slo-mo. We don't have nearly as many phones over here, it seems...but I think I like them better! So what do you get/want, guys? I'm just interested.

Especially now the iPhone seems to have conquered both sides of the pond.
