I just joined and had the same issues:
Spotcycle just doesn’t work – it refuses at the first jump, it can’t find the city list.
http://cyclehi.com appears to have last updated at the end of March. http://www.londoncyclehire.org/ looks OK but I can’t get the map due, I assume, to Java issues, in list form it is OK but there’s no way of filtering or creating favourites, it takes ages to scroll/zoom in etc but is at least up to date.
I have resigned myself to having to do a scary v 4.6 to v5 upgrade on my Blackberry to be able to install the Aztux app AND pay for it.
