Net zero hot spot

I believe it uses the Sprint data network, so not as wide coverage as either Verizon or AT&T.

I have ATT's hotspot gadget and it works okay, but I got it not knowing that my 4S has it's own tethering capabilities. It used to cost extra to tether from a smart phone but not anymore and now I'm locked in to a 2 year contract.

I've got a friend who has one. She uses it as a back up to the park's wifi. She only actually uses it a couple times per month. She is still looking for a better alternative. I'm not sure why she's not real happy with it or if it's just thinking that technology will improve like it tends to do.
