Blackberry vs iPhone debate

So my cell phone contract is up in the next month or so and I am debating what my next phone should be.

I have had a blackberry pearl for the last two years and I have also had a second bberry (world edition) for the last year. I have to say that I am generally not pressed with the pearl. I frequently have to remove the battery to clear the cache completely and when I don't (like yesterday) I loose all of my emails and call history. The world edition didn't seem to have the same problem but that could also have to do with the fact that it was hooked to an enterprise server.

Now mainly will use the device for talking and emails. However, I have been known to send myself recipes and use it in the kitchen. I also highly addicted to blackberry messanger to communicate with my friends.

I am using our iPod touch right now to type this post. I like it although I am no sure if I really like they key board that you can't feel (old school I guess).

If you have any insight you'd like to share I would be willing to accept it. Right now I can say that the touch has been a great value to our life and adding a phone feature would be amazing. My only other issue is I would have to switch service providers.
