The US model of the iPhone 5s/5c doesn't support band 7, which is technically used in the UK by EE:
I live in the UK and to be honest I wouldn't bother at all with 4G. It's only available in some city centres and practically speaking (i.e. for using on a phone) it's not really better than H+.
I wouldn't worry about it.
As noted in this report, Technological Protection Measures (TPMs) (i.e. CSS) are still protected:
"Consistent with the approach taken in relation to other exceptions, no reference to TPMs is made within draft Section 28B. Effective TPMs which prevent copying of copyright materials will however continue to be protected, separately to copyright protection, under Section 296ZA CDPA, and circumvention of such measures will continue to be prohibited."
I have something similar and as you would expect, the encryption key is wiped after 10 PIN attempts, rendering the data useless.
A linux build is available here. It's an firefox addon file (xpi). I have it up and running on Ubuntu fine. You'll need libpcap installed obviously.
You need to make sure you run firesheep-backend --fix-permissions as root manually before it'll work. You'll find this in Firefox's plugins directory.

Standard passenger airports in the UK have used birds of prey for this purpose for decades...
I'm sure the same is probably true for airports all over the world.
I wouldn't be in any doubt that the Chinese would decide that it's illegal. You can't really just call it "Connecting to your home computer from China" when the only reason you're doing that is to circumvent their filter. It'd be a pretty feeble defence!
