This is really a excellet and cheap card on the market. I brought it for my SonyEricsson S500i phone. The sonyericsson website says that max supported capacity is only 2GB but I came to know that most sonyericsson phones accept upto 4GB capacity. (compatible phones listed by Play.com in the proudct description ). The actual memory capacity now showing is 3904MB after inserting into the phone.

I thought I would go for 8GB but that is expensive around 40quids. But with 4GB, i have a music capacity of some 750 songs of 5mb each. With advent of such high capacity memory cards individual mp3 players become useless. Why do one want to carry two gadgets in the pockets if we can combine same into one beatiful mobile phone. Same is the case with advent of 5megapixel and GPS phones. We can be less of gadgets, chargers, cables, adapters, batteries, etc. I searched so many shops for this card and Play.com is the cheapest with its free delivery.

i bought this for my k800i it has plenty of space for music pictures and videos and it is such a small price
and it also is compatibke with the psp
i recomend

Does what it says on the tin. Reasonable price and works the way it should. Delivery within a few days (3 or so, if I remember correctly).

I've read a review somewhere that mentioned that, with larger card sizes, the Sony Err phones take longer to play songs when you select them (though they play smoothly when going through an album or playlist). I've noticed a tiny lag but it's less than a second so no quarms, really.

The only thing I'd suggest is perhaps getting 8gb instead of 4. You can never have enough songs on your mp3 player!
