so, one way to get fresh themes for your nokia series 60 device(s) would be to access sites such as that linked in the post immediately below, or much larger selections which i've referenced before from, for instance, mobile9 or zedge. lots of free stuff out there.
or, as posted in late august (link), you could check out astod.com which provides a very user friendly on-line tool for creating custom themes (including series 60 third edition) - at five bucks a pop. (another option is of course the pc-based theme studio - but it's a bit, um, well, let's say cumbersome, at least for the average user).
enter ownskin - a nice take on the astod model (a bit less sleek, but equally functional), but free. nice. and with a growing community of folks sharing their custom creations.
the hits just keep coming...
