how do i open packs from my phone
Go to theshow.com and log in. The little baseball icon in the top right is what I click to log in with my PSN and then it takes me to the market or wherever I was last time I was logged in. There is a gray drop-down menu button in the top right that pulls up Dashboard, Inventory, Squads, etc... to open packs you already have then go to Inventory > packs or choice packs. To buy new packs go to the Shop.
Hope that helps.
