3 Mobile Broadband Dongle (Take 2)
So, I uploaded a pic of the old white 3 dongle I had a while ago, but I never managed to get that working under OS X. Apparently, sometimes, the software on them goes a little wonky and they need replacing. I tried. 3 said it was my fault.
Anyway, I ended up selling the white one on eBay, and then, last week, someone showed me this site, which, apparently, is run by 3. Despite half of the people on IRC saying "it's a scam!!!!!11!1oneone!!", I tried it, and boom, this arrived. And it works perfectly. So, for now, I'm keeping it. :)
Also, it already has some credit on it - I'm not sure how much (and 3's site doesn't say), but I managed to get online quickly when I was setting it up and 6MB went through no problem.
