Well, to write a review here, actually I havent bought Sony Xperia myself but I used it for a month which I borrowed it from my friend. The item is superb. We can say that its a mini computer. The phone has OS like PCs do have and can be use it wherever you go. The display is very good compared to other company phones. One thing I want to say is about its Camera. It really rocks!! From what I've experienced is that the loud speaker is not that good for playing MP3's very louder. I've played many songs . But if you use the earphone its very good. I got the battery backup of 3 to 5 days when its standby. The camera quality is very good. Its equal to the digital camera's quality. It has easy touching QWERTY keyboard which I liked it. I dont know the WAP speed but GPRS is very good here. I could browse the internet with a good speed, a mobile could have. Yes, it has GPS system. It was working fine but sometimes it got struck.
Finally, I would prefer this item for anyone who is liking to buy this.
