Is there any code that does this with Arduino software version 1.0.1?
Of course there is. Reading data from a client is not much different from reading data from the serial port. There are tons of examples of how to do that.
The difference is in how the data is delimited. The serial port remains active when there is no more data. The client object does not.
But, if you can read and print to the serial port all the client data, you can read and store that data in an array just as easily.
