The SL45 uses a
flash card for memory and comes standard with one that will hold 30 minutes of
MP3's. The phone also features an orange backlight, which instead of just turning off, fades out.
Infa-red is yet another feature of this phone along with several games,
email accesability etc.
Unfortunately, only months after its release the SL45 has been superceded by the
Siemens S45.
