New cell phone?

I got a SonyEricsson W750 who is about to go home any day now.... Some days I can't call out and some days noone can call me. Thats no good feature for a cell phone. I have always been a SonyEricson guy but now I'm not sure... I really like the new Nokia N95. It's got a ok size. Mp3. Video. GPS. 5 megapixel camera.
