i have had my phone for a good couple of months now and for the most part it worked fine, however after dropping it a few times the lock/power button has fell off. this wasn't much of a problem as i could still lock it with my finger, but now i can't lock it with my finger or turn it off and on. i was using it and it ran out of battery so i charged it up and it came up the sony ericcson screen with a battery charge sign but i can't use the power button to turn the phone actually on, is there anything i can do to help this apart from send it away?
