just installed v1.60 update, was trying out the bt keyboard/mouse option which i was able to register and use my bt keyboard with no problems. i bought this keyboard on ebay for $16.50 and $12.49 shipping, pretty good deal in my opinion. Now here comes the ironic part of all this, the brand of the KB MICROSOFT haha. ive tried the kb in RFOM, dvd playback, websurfing it works great.
f.y.i. they still got plenty on ebay hopefully it will save my fellow ps3 owner a little bit of cash for accessories.
