well, thats amusing. i've gone through a fair few phones. after my w810i died, i spent a long time looking for a phone that would be unique. i have a practical nature and thought it wouldnt be so bad having a retro phone, i had my eyes set on that sony but they kept selling for over 20.. i bet its a brilliant phone at heart.
to conclude, i don't have a favourite phone, because theyre all rubbish for one reason or another... no matter how "helpful" they can be... >.<
