I don't actually own this phone, my mother does! I do, however, own a V630i, which is very similar but a few minor differences. The W810i is much slower, for instance. It syncs well with windows media player, which is what I use to transfer music. But personally, if You are looking for a bargain, get the v630i! Its £20 cheaper and comes with a free pair of speakers!! Besides, ive been with T-mobile in the past, and they tend to be quite expensive.
