I feel like using two different phones (among other things) creates a variable that messes with the test. Hasn't anyone watched Mythbusters? Gosh.
Well point was to use one phone thats on the 4g lte network and one on the xlte network. I doubt using both at same time does anything since im sure thousands of other people nearby were on their phones in los angeles as well. Plus each phone was on a totally different account if one would think it might have any effect if they were on same account.
