2010-07-03 I just downloaded a dictionary app for my mobile phone. Dictionary by Vikrant for Sony-Ericsson C510. This should help, especially during times where I'm not around a computer.
To install it, use the cable and let the phone act as a storage device to the computer. 2 separate drivers will appear. Copy the jar (do not unpack) into the Other directory. Disconnect the phone from the computer and let it restart. Go to "Organiser & Tools", My Files, Other and click install on the jar.
