You can choose one from three styles - I&C, Lighthouse and Dog (move cursor over picture for animation).

But in firmware several animations exists, which are not used in C35i

Animation of safety box is probably from S35. Phone moved away is suppressed and replaced by I&C logo. And for what is logo of French service provider Itineris (CC 208 NC 01)?

Last, what we can see on display during phone switching off, is URL of Siemens site. This address is in memory stored not like text, but like bitmap picture. In firmware version 18 is left picture, but in firmware version 21 is right picture already.
