Is Linux a "True UNIX"? (no.)
There is no true 4G. What's new here? There are higher speed cellular solutions and many are out but if you want to ask the 4G question, then start with asking who defines "4G".
That would be you in this case.
I'm sick and tired of all these mobile carriers and tech sites referring LTE and HSPA+ as 4G! 4G does not exist yet.
4G requires speeds of more than 100mbps which LTE-Advanced will bring. This link may help to explain. http://gigaom.com/2010/11/04/what-is-4g/
