Not sure if this is an option for you, but I plan on bringing my ipad or laptop with me to my shows. But, if you are at a show without wifi this may not help. I have ATT and I can make my iphone a wifi personal hotspot and any device that is wifi enabled can connect to my hotspot (they have to have a password, so no worries with others tapping in.) Worth the money really, because no matter where I am at I can access the internet and keep everything real time.
