The phone still works for now, but probably not for much longer, and the sweatshirt really isn't my style. Any suggestions?
call the last number the guy called and tell him that you got the mobile of his buddy and tell him to pick it up.
create a sweatshirt embedded cellphone! (DUH)
talk to some investors and get them behind you.
form an llc and create a business.
send your plans to china where they will make the mold and mass produce. create a landing page for your new product.
run some targeted traffic to LP based on researched demographic.
profit.
