No I dont have a tutorial on a phone mate.....google it. Like I said mate it will also depend on what phone you actually want to make?? a modern one, a mobile, or an old bakelite...which is as old as me LOL....looking at your query..I would ask how much Maya have you done? It appears (sorry mate the syntax is hard..English isnt your native tongue?) you want to make a phone and animate it to come together...so starts with parts then the phone gets put together?
This will depend on how good your skills in Maya are...if you have just started this will be a difficult project for you....and if you havent done much modelling maybe just try the phone itself without modelling the inside parts for now. as an old bakelite will only have about 5 main peices this will get you into the mood.
Have a look at these
"A Darkness at Sethanon", a book I aspire to model some of the charcters and scenes
