Yes, was in GASIL 9/09. The reason given was a rapid decline in the use of the service.
Not sure about iphone (maybe the simplest solution), but you can get lots of the services of a Blackberry more cheaply with a web & walk service from T-Mobile (10 quid extra a month), together with laptop and bluetooth & surf-capable phone. Hey presto! Net access, e.g. Met Office website, POP3
Very handy when out in-the-sticks.

NB works with T-Mobile UK, but not necessarily with T-Mobile in other EU countries.
