My new phone doesnt work

I just got my razor less than a month ago. its been working perfectly fine until like two hours ago. the problem is the key pad. the end button is the only one that works every time. 0,1,3,5,7,* send, clr, and the two top buttons dont work at all. 2 did work, then it stopped, but will sometimes put in 8, and when i open the phone its will act like im holding down and constantly pressing 0, and sometimes the same thing will happen with 5which will sometimes cause it to try to call this kid alex, whome im guessing is the fifth person in my list. my menu button works. but if i go in there the arrows seem to be jammed too, because the screen just races through all the options in the menu. i admit i have dropped it once or twice, but it was never from much height and it didnt ever hit the ground very hard at all. i dont recall ever dropping it recently, but im pretty sure i havent dropped it in a while. i think the reason why it might have messed up is because i left it on the bathroom counter when i showered. the steam and/or hummidity might have done something.. but i do that all the time so i can hear my phone when it rings... and ive never had any problems until now. i dont know what to do to fix it, or if its eevn fixable. im hoping that if i leave it alone, it will dry out and maybe work again. thats what my brother did after he washed his phone with the laundry and it worked! and mine cant be that bad.. well.. HELP please
