I've had it for a week and I am on my second one. This one is going back also. The operating system is bad! I can't use the ringtone "Grand Canyon" that came with the W518a. Get the message?"cannot use this file". Also I've been in contact with Customer Service with many issues and they have decided not to return my emails. Isn't that a great company to work with? I can't use any of the ringtones I downloaded from my MAC and there are NO updates for the Operating System for the MAC! When I open my old Sony Ericsson Z525, I get 4 to 5 bars. With the W518a, I get 1 or 2. This must be Sony's cheap end phone made for no-nothing customers so stay away from this cell phone.
