Phone just arrived, is very light, accepts all of my SIM cards, is very LOUD when tone is set to 4 out of 5.
I will probably hear it even in highroad traffic on my bicycle. It takes the same battery as the N900, so may be just anice way to get a cheap battery and a phone , and the charger is the same as for the BH-905, but not like the one for N900. Phone call quality is, as expected, pretty good.
