What is Verizon s cheapest data plan for iPhone 4?

I currently have the 2 GB of data on my iPhone 4 and was wondering if there's any different/cheapest plan. I want to know because I have a mobile hotspot from Clear so bassicly don't kneed that much GB. I want to know if Verizon still has the $15 plan as well.

1GB of data for $50 per month.

I have a smartphone pack?
that's $40 a month unlimited data and unlimited texting. I have 1200 minutes but I know for a fact I have unlimited data because I use data 24/7 on my phone and it doesn't charge me.

Why don't you just get that?
