I am on my 5th Blackberry. I also have an iPhone that I used for a couple months. I need two phones to have my regular cell number and capture a landline in a different zone from my home.
I have the iPhone forward to the Blackberry. I find the iPhone very irritating that I have to swish it to get to the email instead of having it on the screen. I never browse on it because I use my iPad for that. Voicemail and email are all I want on a phone.
