Hello? Hello?

Been itching to buy a new mobile phone or PC lately. My current mobile phone needs to be replaced soon. It's become a text messaging device cum alarm clock rather than a phone. Not sure if it's because of the battery (the second one so far) but the phone dies 5-10 seconds after I answer a phone call or make one. Talk about frustration. Any phone model suggestions? Nothing too high end and complicated for me (like Nokia's Communicator type models). Am thinking of the 6510.
