There are two main reasons why there is a discrepancy between listed capacity of the memory card and what shows up on your computer. The most likely reason that your 512MB memory card shows up with only 485MB worth of capacity is due to the small discrepancies in algorithms and file formats by various operating systems.

Ordinary cell phone service works so that the unique serial number in your phone (its ESN) is used by the cell phone service provider to identify who you are. The wireless service 'knows' that a particular phone's serial number is your phone and knows to send phone calls to that phone when someone dials your phone number. A GSM phone is not directly linked to you. Instead, it has a removable account card, called a SIM (subscriber information module) and this SIM has a unique serial number on it.
