I've got a really really cheap quite thick jelly case thing for my HTC One X and I am pretty sure it's laced with lead or something because it completely knackers my WIFI and Mobile signal (maybe it's a coincidence but it seems to have become even worse since upgrading to jellybean).

I think I will splash out and buy a half decent one, so what would anyone here recommend? Do I need to still with the official HTC ones?

Ta!
