I will be traveling to the UK in about a month, and was planning on just bringing my iPad instead of my laptop. It's a 3GS device, so I think I can get a SIM from one of the carriers there.
Since I will only be there a few weeks, i was looking for advice on which carrier would be best. I just want to get a SIM and buy a few weeks of access, without having to enter into a long term/auto-renew agreement.
Can you just go into one of the carrier's shops and get one?
