I'm looking to get a new phone for my birthday since my Samsung Soltstice gets barely any service on my college campus. I have AT&T and I have a friend with AT&T who has a Blackberry and she gets full bars. But I've also heard great things about Androids. The one problem I have with them so far is that they're so big and bulky and I don't want to be carrying a brick around campus. So which phone is more desirable?
