Currently on Giffgaff. Becoming irate with the unstable connection, inferior speed and piss poor response to my abuse of their terms and conditions. They banned me for downloading 12GB of data in one month, and sent me an ambiguous email that pretty much said that I violated their terms, but not how.

I sent a lengthy mail to them stating (lying) that I wasn't tethering, but was using an X86 Windows XP phone. My attempts of deceit would have failed if I wasn't a master of manipulation.

To summarize, all good, unbanned, but am not impressed with their 12GB limit. Looking to go back to 3, but signal is pretty bad around here. T-Mobile won't be any better, but I'm not certain whether or not they capped speed on their new ridiculously named plan. Will have to find time to look back into it again.
