You are assuming that Apple and RIM implement email access the same on their devices. I believe this is incorrect. I believe the iPhone (and all other smartphones other than RIMs) allow you to access your email by directly contacting your email server. RIM, on the other hand, goes through an intermediary server run by RIM. This is why as recently as last December, a failure on RIM's part caused delays in sending/receiving emails on their devices. This couldn't happen on an iPhone (short of a OS update that breaks your email) because Apple plays no hand in the delivery of your email.
If the patents in question cover a technique where there is such an intermediary server, it could apply to RIM devices by not to Apple's devices which, as many have pointed out, are really no different than checking email on your home computer.
It could simply be that these guys are trying to leverage the fact that they won the RIM case to convince a judge or jury that there patent applies to all these other devices when if fact it may not.

Ahhhh. Good point!
I guess when you have 617 million laying around, you're not worried about legal costs so you just go for it with other major companies LOL
