Nokia BH-905i ... now with less "suck"

My 905s never crashed with my other Symbian headsets, but the crashing with the N900 is truely truely irritating.. Especially if whilst you're wrestling with the headphones trying to get them to reset, the N900 decides it'll resume playback through its own speakers.. grrr

Maybe these updated headphones will have a better bluetooth firmware
