Phone acting odd after power outage

[Gulanowski]

Dunno if you guys watched the weather but two nights ago we got hit pretty hard by an ice storm up here in NH. Anyhow, we lost power for a few hours and my phone was plugged in when the power went out. I noticed as the day went on that the front, left soft key (default: calender I think) needed more pressure to work, no biggie. Plugged it in last night and unplugged it this morning, went to check my web-based email and half the keys either didnt work or needed more pressure to worked. Touch screen was somewhat responsive at best. soft-reset and pulled the battery for a few seconds and everything seems to be good now, but i'm still concerned nonetheless. Think these problems could be contributed to the loss of power or is this something else?

thanks guys
