marketing at its finest... the 4.7GB are marketing Giga Bytes - with a base of 
1000 rather than 1024. Some people us GiB to indicate that they really mean 
1024 base. For GB to GiB you have roughly -7.5% difference. 

4.7 GB / 1024 / 1024 / 1024 * 1000 * 1000 * 1000 = 4.38 GiB

You'll see the same with virtually all storage devices - including harddisks. 
Read the specs for your harddisk and then check with fdisk or something like 
that how big it really is :-)
