Best deals on prepaid iPhone?

[what4]

I'm a fan of Cricket (uses AT&T), because of the combination of relatively cheap data and excellent coverage. $55 a month for unlimited talk and text, plus 10 GB/mo of data.

There are cheaper plans with less data.

FWIW, Cricket limits download speeds to 8 Gbps and officially allows tethering only on selected phones purchased directly from them.
