Last problem with Treo600 was when using Ptunes to listen to MP3’s and no sound was coming out – stupid me had disabled the loudspeaker with the cunning ‘silence’ switch on top of unit. Oh well Tim at www.normsoft.com the makers of Pocket-Tunes sent a smiley and said other people had contacted him as well. However still having problem with earpiece not working with MP3’s although in US manual it indicates that maybe it shouldnt. I find that difficult to believe so will trog of into town to buy headphone adapter.
Its amazing the difference between the USA and UK manuals. The American one has a LOT more detail on how to use and keyboard shortcuts etc.
