The claims also do not mention particular devices, referring to them as transceivers, claim 1 as an example :

Finally, you picked the worst patent to say it doesn't apply, as Motorola already has a favorable decision with this one in their pocket against Apple in the EU (with the EU equivalent patent obviously) and people think Apple will lose the appeal scheduled in February.
I understand this but if you look at what they are patenting; it had been around for a long time before the patent was issued. There were chat systems long before 1995; some of which did operate on phones. But it shouldn't be hard to show that being a wireless devices (the Transceivers don't have to be wireless) doesn't matter, the underlying technology existed and thus anyone knowledgeable in the industry could easily implement this with what existed by changing the transport media. Thus should be invalidated. More specifically, in this case, the application layer is basically the same as something like IRC, but potentially the transport layer is different although the transport layer is never called out. The patent is an application layer claim.
My guess is that the defense attorneys are not attacking the patent this way. I don't know the details of the ruling in the EU but it looks like it shouldn't be holding water but it is. Not sure why.
