Is sprint worth switching to for the cheapest iphone plan?

I currently have at&t I'd like an iphone or any type of smartphone… But their plan is to pricey for somebody that likes to text and browse the web ALOT. Would sprint be worth switching to?

Sprints slow.
Everyone I've heard talk about sprint absolutely hates it.
When you upgrade you can get unlimited with at&t. Or get Wi-Fi and not pay for your internet through your phone--the cheapest way.

I have sprint and it is in comparison to the price we paid for Verizon, but we get free mobile to mobile talking… So we never go over our minutes. Currently they are upgrading their towers from 3G to 4G in Michigan. I can assume this will be done in most states. So yes it is worth it.

Sprint has the slowest network of all the major carries.

I would advise against it.
