Imagine my surprise when I finally got my hands on the proper Motorola Mobile Phone Tools, only to discover that it won’t let you change ringtones or wallpaper on a C350 phone, even though the C350 has a colour screen and comes pre-loaded with some very sucky yucky images and tones.
Anyhoo, I found a friend with a WindowsXP machine and – with some trepidation – loaded P2KMan. And it worked! Well, ringtones seem to be a bit of a pain and I haven’t got them working yet, but I managed to get some of my own wallpaper uploaded. You do need to be very careful with P2KMan, though, as it’s possible to damage your phone by deleting essential files.
Images for wallpaper or screensavers should be GIFs, preferably 96×65 pixels. Animated screensavers can be animated GIFs. You can find rather more info than you’re ever likely to need about creating images and ringtones for the C350 here (PDF file).
I’ve also knocked up some simple guide images – a transparent GIF and a Photoshop / Elements layered image that show the safe areas for your wallpaper, so you can see which bits will be obscured by the battery icon, time, netwok ident etc:
