I have a android phone 2.1 but this keyboard be simply not work no this version of the phone . the keyboard work great and be quiet and work for I specially with my pc where I have a belking bluetooth dongle . be easy to pair to my pc and work perfect specially when i just want to have my arm on my chair rest without have to type with the big keyboard and the big key , unfortunately it doesnt work on my android . the problem be when i run the application for the bluetooth keyboard to work , the application ask that you need to be connect on internet , which I do but the application just close and stop thats it . I think be because of the version of the android be a bit older . I will try on a new version on another android phone and see if it work . its a little tricky right there about the keyboard to work on you phone . you just have to open the cd that come with the keyboard and then you have to go to the android folder -lrb- in my case -rrb- and copy the application to you sd card . after that go to file manager and just run the application . the application will automatically install and run but in order to the application work you need to be connect to internet and that will be all you need . Hope this will help you . with other model phone oyu have to open the folder of you operating system and do pretty much same thing . for better guideline open the Manual pdf on the cd .
