Deutsche Telekom has been doing this for a while - that's why there's a reclaim magenta petition out there and an all-pink photo group on flickr for those of you who'd like to join the protests.
But when T-mobile stayed down south before, they were mainly concerned with German and Dutch companies. They're now going after another telco - namely Sweden's (and now Denmark's) hot pink Telia.
At least in this suit, both companies are actually providing the same service, however, the magenta's aren't quite the same.....
(sorry about the lack of posts today, busy busy you know.)
