Hi @Three_Rachel. I've just checked my account and the strange add-on is not there anymore. Thanks a lot for sorting that out, I really do appreciate it!
On a side note, the 4G seems a no-go for me, but I might be getting some more luck with 3G. Don't won't to jump the gun, so I'll keep an eye on it for a day or two before I update the other thread with my findings. Thx again!
