T-Mobile MobileTV
Update 4: Hurray! Got it working. I don’t know if this was the issue, but for the interest of others, while I was at work last night, I found my whole internet wasn’t working, couldn’t get on Facebook, Flickr, anything … I remembered somebody saying once before that if you’ve used your laptop to connect to the ‘net via bluetooth on your phone (which I have, at my brother’s wedding a few weeks ago), it creates a new connection profile on your phone which sometimes causes conflicts, and is perfectly safe to delete (a new one will be created next time you connect from your computer). It hadn’t caused any problems till now, but I figured why not delete it anyway … and now the mobileTV works fine. Better than fine 
The picture is a lot better than I expected. I watched Mitchell and Webb and The League of Gentleman while walking home, lol. Very strange 
I have to be careful with that “Big Brother” button, though … there’s something about having the live feed in your pocket that makes it strangely appealing …
Making a separate entry on this that started in my entry on LazyTown, ‘cos it strikes me as interesting enough to warrant a spot of its own.
While I was fooling around with my phone (adding my LazyTown theme), I discovered that T-Mobile have launched their MobileTV service 
And one of the channels is Nick, whoohoo! lol. They have a 24hr pass and a 30 day pass. Till the end of the month the 24hr pass is free (presumably you only get to do this once – I’ll update when I activate mine), and the 30 day pass is £3.50 which sounds reasonable to me. This probably doesn’t include data transfer, I’m guessing, but I’m on Web ‘n’ Walk Plus which allows me 3Gb so I should be ok whatever.
Update: Well, I activated my 24 hr pass, I won’t know till tomorrow if I can do it again but I can’t find anything on the website to say I won’t be able to. It also implies that this doesn’t form any part of my Web ‘n’ Walk allowance, except for the HTML/WAP pages that comprise the menus etc. Which is kinda cool, but I remembered one thing that makes this all make more sense: it’s not the same kind of mobile TV offered by some other companies … this is specially edited content, short clips of shows and stuff, probably never more than 5 minutes. So it won’t be a lot of data transfer anyway, even if you watch the whole offering. But I’m still speculating … I’ll check back tomorrow when I’ve had a good play around
Update 2: Doesn’t seem to be working for me yet, but I imagine that there’ll be teething troubles, the FAQ says “at full capacity” it will slow so try again later. Speaking of the FAQ, I loved this entry:
Also in the FAQ, I discovered that the content offered is “a combination of live TV and edited highlights” ... certainly not the short 5 minute clips I initially expected … it has a built-in cut-off of 1hr (you can instantly reconnect) which I think says it all. This could be very cool … if it ever works, lol.
Update 3: Well, my 24hr pass expired without my ever getting to watch a second of TV lol. The good news is, the price tag on the 24 hr pass still reads as free. I’ve activated a new one but still no luck with getting a “signal”. Apparently the error I’m getting is known by T-Mobile, though, and they’ve had dozens of complaints today already. I’ll just keep at it. It’s not like I’m away from the actual television much of the time
