Just to add to the E+ 900 vs. 1800: Orange France uses 900/1800 and my phones all suffer from the buzz but not always and not reproducibly. Except with the headphones, they can make it so loud the communication becomes impossible. _______________________________________________ support mailing list support@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/support
