Now the iPhone has gone to 3G, I am seriously thinking about trading in my BlackBerry. The biggest problem (for me) is that attachments on the BlackBerry are limited in file size. i.e I can't attach and send anything 3mb+. I can receive 4mbish tops but anything over, I get the message "email truncated due to file size". I really need to be able to send and receive attachments much larger than this if I am away from my Mac. I subscribe to .Mac and figured that the new iPhone should work really well with my macmail/Safari/mobileme. Is it time to ditch the BlackBerry and go for the iPhone? Any opinions or facts relating to switching to iPhone and the attachments would be greatly appreciated. Thanks.
