I have had a lot of trouble with SE phones, mostly they had bad signal pickup. Since then, I have had three phones from Nokia, and they have all had fantastic signal reception. The look of the Nokia phones may not be as appealing as the SE, but damn are they good solid phones.
At the moment I have a Nokia 6585 and I love it. I have had it for two years now, and I wanted to get another one, but unfortunately they are out of production, but I will definitely get another Nokia. That is unless the iPhone comes out and is awesome.
