So after a couple weeks of deliberation, yesterday I picked up a used BB Curve 8900, switched over, and retired my iPhone. I was unsure about whether I would be able to adapt after a year on my iPhone, but after just a few hours, I know that I won't be going back. Here's why: Complete customizability Every aspect of the BB can be customized to your liking... how many vibrations are given off, font, profiles... part of why I love my Mac is that it is completely customized the way I like it. The iPhone gives only the most basic customization options. Options for everything Every conceivable option is available... native support for folders and hiding icons, dealing with messages, etc. Always-on IM There really is no match for BBM... every BB user has it, it's always on, there's no service to sign in to... really a genius move by RIM Fast OS This might be a product of being jailbroken (which was necessary to get some basic features I required), but this BB is miles faster than my iPhone. No lagging, no stuttering. Real multitasking Push notifications were neat, but the BB can do real multitasking. Leave an application running in the background while you check something else. Better notifications iPhone's notifications were really lacking... the BB has an LED to show notifications, as well as statusbar icons (something I needed to jailbreak for on the iPhone) Now, there are some things about the iPhone I will miss... Seamless syncing with my Mac I had to use a PC to get my contacts over, and I'm not even going to try moving my calendars over iPod 'nuff said Uncrippled wifi When connected to wifi on the iPhone, every data feature was available... I'm on an unlimited email BB plan (no actual data allotment), and a lot of features are unavailable, which is annoying So there you go... I had my iPhone for a year, and I really did love it, but the BB is just a powerhorse.
