Without 3G support the $30 price tag is WAY too much. I know that is not Sling's fault, it is AT&T. But I will have my laptop anywhere I go where there is Wifi, so why would I chose to watch it on my phone?
The only REALLY appealing thing about this application is if it ran on 3G. As it, $30 is just way unreasonable.
I completely blame AT&T on this one. Basically, they said their network was too lame to have all these iPhone customers slinging their content. YOU NEED TO UPGRADE AT&T! The only reason that Blackberry's are allowed to Sling over 3G on AT&T is because not nearly as many people who have Blackberry's are this tech savvy to sling. But iPhone users have shown to REALLY use their phones to the max, and it scares AT&T that their networks would die if they allowed it.
Oh well.
