In reply to Andy Hudson:
You will be able to use it for internet browsing, but you will be charged an extortionate number of pounds per MB for the pleasure (their non-bundle pricing seems to be about 4 years out of date...).
Don't know if it's a "smartphone" but I've got a Nokia 6220 at the moment, which is an "s60" device. I've used WAP for checking email, forecasts, headlines, etc. for most of the last decade, but it's really only in the last year or so that I've used the mobile for more regular internet browsing. If you download and install Opera Mini for your mobile then it allows you to look at most normal internet sites - including UKC - with ease... I now use it in preference to the inbuilt browser on the phone.
