"Last week, I was contacted by a small company that I'll call Unlocko.
Unlocko sells software that "unlocks" mobile phones so owners can
select different cellular providers on the same handset. The company
had received a cease-and-desist letter from a large mobile phone
provider, which I'll call CellPhoneCo.
Like most U.S. cellular providers, CellPhoneCo electronically locks
the handsets it sells so the phones can only be used with
CellPhoneCo's service. CellPhoneCo claims that the sale of unlocking
software is illegal."
