Which is why I referred to it as Nokia's implementation of Symbian, by which I meant S60. At the time the N70 was released Symbian was not controlled by any one company, with both Nokia and Sony Ericsson controlling the majority of shares in Symbian Ltd, although Nokia had strong control over S60.

Aside from a few half-hearted attempts from Samsung and LG, the only really ambitious attempt by a company other than Nokia to use S60 was Siemens with the SX1. Unfortunately it was not much of a success, due in no small part to the odd keypad layout. So for all intents and purposes, S60 equalled Nokia.

UIQ, similarly, was driven primarily by Sony Ericsson although it was owned (till 2007) by Symbian Ltd. Unlike S60, which was in some ways a scaling up of Nokia's dumb phone interface to a smart phone, UIQ was designed from the start for stylus-based touch input. But both co-existed, with the SE P800 and the Nokia 7650 having launched as far back as the second half of 2002. I always preferred UIQ, to be honest.

Both S60 and UIQ were abandoned when Nokia bought out the other Symbian Ltd partners in 2008.
