I feel like I'm in the same boat as you OP. I've been extremely tempted to switch to a Bold 9900 so much. Trying my best to hold out until the BB10 QWERTY device though...

I know! It's so tempting.... I feel like society will hate me when/if I switch over.

People will look at me like i'm crazy when I tell them I switched my iPhone for a BB.

I am not sure why BBM or iMessage are even relevant anymore when they force you to message within the same platform, Whats App puts them all to shame being cross platform and syncing all your contacts using it...

I don't know anyone using "Whats App", most of my messaging contacts have iMessage.

Back on topic, I have a 4s and a corporate 9930 (Used to have a personal 9700). Both great phones, the keyboard on the 9930 is the best keyboard on any phone. The touchscreen keyboard on the 4s took me a long time to get used to but I am finally comfortable with it. Both phones have good screens but the 4s screen is better. The camera on the 4s is certainly better than my 9930's would be if my 9930 had a camera.

Unfortunately and unsurprisingly, where the 4s leaves the 9930 in the dust is the OS, applications and ecosystem. BB has BBM but I only had two contacts, I have many iMessage contacts (my 9930 is an employer supplied device so no BBM and no camera).
The BB has no video calling, the 4s has FaceTime and Skype. The gmail/google calendar integration works better on the 4s and iCloud means I don't have to use google contacts which totally suck (9930 is hooked up to BES). I don't use siri.

Aside from the keyboard, the feature I most miss on the 4s is the message indicator light.

You should get a BlackBerry Bold 9900 I think it will be a nice alternative. I mean App store provides 650000 apps that you're probably not going to make use of like 95% so why bother to have an iPhone?

get the 9900/9930. I wouldn't wait around for BB10 because there really is no solid release date. You also mentioned wanting a keyboard and its no telling when a BB10 phone with a keyboard will be out either.

I think the 9900 is the best Blackberry out right now. Cant go wrong with it.
