regarding the unresponsive keyboard, I too have experience this after a recent trip...

so do you fly often/ever? if yes, did this problem occur AFTER you took the phone on a flight?

for me, its not that bad, but I do have to press firmly and surely for the key to register, typing as i had previously result in many missed key.



as to unresponsive unit, i sorta feel that too, but there's an overclocking app floating out there, you should see if that help or not
