Seems neat - except for the $10per GIG part. Arrrrrggg! If you use a lot of data on 4G it's not going to be any good.

What I'm really looking for is a 4G (or even a 3G) wireless data plan that I can use as a hotpsot with unlimited data. Thus far I find nothing of the sort available in the USA. If anyone knows of such a service - please let me know! I get unlmited 4G data with my t-mobile account - but it only allows me to use 5gig a month of hotspot data with it..
