For thumbtyping, I think it will be better if some accessory came with the old alphanumeric type (like in Pearl 9105? or common candybar phones)
And, yes, I cant type with one hand even on my Bold 9650
How do you connect this to the PB??? It's paired via a usb adapter.
search for it in youtube- there are a lot of setup demos in there. Well you're right probably nothing about playbook setup..but I think I did see one about bluetooth pairing
