TRUST ME when i say I feel your pain.
I spilled a glass of soda on my ReZound 1 week after the 14 day no questions asked return policy and I was pissed. All I could do was exactly what has already been recommended to you.(although I could only manage to wait overnight before checking my phone) I pretty much dodged the bullet as my phone still works but there are some after effects. I sometimes get little weird things that happen, but it's so infrequently and so subjective that you sometimes wonder if your mind is playing tricks on you. Like when I first got the phone it seemed like the voice recognition was spot on. Since the spill it seems to get what I say wrong more now. Also the biggest thing was from time to time the top of the screen would have a greenish tint that faded in and out for a while then go back to normal. I finally caught a screen shot of it one day when I was on the phone which I've attached to this post. It seems like I have to be multitasking on the phone to have a chance of it happening. It functions fine otherwise but when your phone is still relatively new any issue. especially one you cause yourself will bug you.
