Even the subsequent purchase of twice as large MicroSD card with 1GB of memory has not caused problems in my phone. Bravo!
Now I have (about 25.- Euros) again slammed with this really brilliant offer and opted for the even greater card with 2 GB, knowing full well that my Nokia 6131 would be not really geared for it! But on the contrary !!
Leaving aside the fact that the music player is required (over 400 !! MP3s) just under 1 minute to load the vollbespielten disk that everything runs smoothly and flawlessly! As songs memory.Simply absolutely TOP awesome! The day is not far off that expensive MP3 player (AAC, AAC + etc. - see iPod) are unnecessary, the mobile phone is the future probably can not assume these functions quite ...
Conclusion: Ingenious media from SanDisk (512 MB, 1 GB and 2): here another 5 star recommendation!
