I use the phone Sony Ericsson W350i Electric Black Contract Mobile Phones without branding, no Simlock now over half a year, where I belong clearly to the Little-callers. Even the Walkman I need only rarely. The phone I still like the look and the features forth good, but I am annoyed actually constantly about the short battery runtime. Even with low utilization should I recharge the battery after 3-4 days. That's why I complained about the device, but received by the service company to provide information, it was perfectly fine. Otherwise, I think the MP3 player good, the labeling of the buttons too small and the camera unnecessary. With the flap I previously had no problems, although I carry around in your pocket, the device loose with me. However, the cell phone 1x no longer recognized the SIM card, so I had to clean it and re-insert. I'll invest a little more money for my next phone.
