I have reveived some mails for asking if we will provide the nRF24L01?s hardware SPI demo or library, which we just provide the softwore SPI way before ( http://arduino.cc/forum/index.php/topic,61720.msg446229.html#msg446229 ). So we modified the code used SPI library which you can import from Arduinos standard library.
More information about the nRF24L01?s hardware SPI is here. NRF24L01 with Arduinio's SPI Library - Blog
Thanks and Regards,

In case anyone was wondering what this is about, its talking about the Nordic Semiconductor 2.4GHz RF module, which coincidentally I just happened to be playing with most of today (though not on Arduinos...) - its a reasonably cheap 3.3V module with 5V-tolerant logic that does 250kb/s, 1Mb/s and 2MB/s modes and has inbuilt packet handling.
I do not understand how to set up a speed of 250Kb, there are only 2 possibilities 1Mb or 2Mb. If someone can clarify, thanks.
Ah, I think the 250kb mode is only on the nRF24L01+, not the older nRF24L01
