I have not owned an iphone, but did own an itouch for about a year, which is basically an iphone when it comes to wifi. I was happy with my itouch when i had wifi it worked well. I currently have a blackberry storm and got rid of my touch because the storms media interface is great. I believe the storm has the same interface as the bold.
Besides that the iphone/itouch are definitely over hyped from what i have read and heard. if you are using this for work it may be beneficial to have a phone with a physical keyboard for emails etc. Blackberry's are blackberry's after all so the email is top notch. blackberry's are more of a work phone, but are gradually adding a few extra nice play features. the iphone is a dumb phone playing to be smart. I don't see the iphone being a good work phone, especially being that people are dropping calls left and right on AT&T's excellent service.
I am torn between buying an iphone or a blackberry bold. I already have at&t and am ready to upgrade. I had a blackberry, an old version on nextel,but recently cancelled my service with them. I liked my blackberry because of the mobile web features and the ease of setting up my email so i could get my messages anywhere. I do occasionally use gps navigation on my cell phone and in my new job it will be even more important to have very good web acces and filing reading on my phone. Which phone might be better for me? Any hlpe would be appreciated.
