The beauty of this keyboard is that it’s able to connect many type of devices and smart phones, here is its specifications:
Work with Microsoft Windows Mobile 6.0/ 6.1 or later system mobile phone
Work with Nokia Symbian S60 system mobile phone
Work with iPhone (built-in iPhone OS 4.0)
Work with Android system mobile phone
Work with personal PC and HDPC
Work with Sony PS3 player
Good choice for typing email or chatting
Build-in rechargeable Li-ion battery, supports USB charging
Available in AZERTY, QWERTY, QWERTZ with 66 keys
Though it is able to connect to my HTC HD2 Windows Mobile 6.5 phone, but some character could not be typed out at screen, eg. @ #$..., however, this does not bother me, as I’m eying my next smart phone, which is either a Samsung Galaxy Note (May be before end of 2011), or the Galaxy SIII (To be out in the middle of 2012), all two are Android smart phones (-large screen size!) which should works well with this keyboard! :))
