Shall i continue to use my phone?

Sometimes my phone will jam; sometimes still good to use. Still a new phone actually; used since February 2009; just four months away. However, just now when i receive a call, the phone made weird sound for quite long minutes; not sure coming from battery or internal part. I scare one day will explode. Shall i continue to use the phone or better get another one for safety concern? :roll:
FYI, the phone model is Nokia 2600 - phone gotten in a lucky draw

get a new phone if you find the current problems irritates you.
