My nextel does not read my memory card

This same thing happened to me recently. My reader seemed to stopped working after I accidentally dropped my phone at work. I tried everything from formatting it to trying different memory cards and nothing worked.

I manually added the music files on my 1gb SD card at first and figured I should do it again and it didn't work. I then synced my music through Windows Media Player but that still didn't do the trick.

The solution in the end was to take the SD card out of the phone, turn the phone off, put the SD card back in while the phone is off, turn the phone back on, and then update your library. If that doesn't work you may have a faulty reader that came with some of the phone when they first came out.

Hopefully that helped...
