I have to wonder if you need either.
Yphone or Blackberry alike have poor battery life. Unless you really need the extra features of a "smart" phone just get a phone.
Get whatever fits your needs best. I feel like my 9930 just gets things done quicker than on any other mobile platform. The keyboard shortcuts have much to do with that. If I also wanted to watch netflix, play angry birds, sync all my devices (photos, music and videos) without any hassle, I'd think about iOS. But for my needs, powerful and FAST communication is what keeps me carrying the 9930.
