I bought Motorola V600 in replacement of Sory Erricson T610. I have used several cell phones since 1992 and this is the worst phone I have ever used.Phone book scrolling is very slow and some futures in this phone are not good at all. No Doubt that V600 have all the futures and look wise is very attractive but no use. I have been using this phone since November 2004 and now I am sick and tired with this.
