I never use mobile skin, when it popped up I hit full site, but I just reset all cookies/cache, rebooted phone, then tried to login using home ISP wifi on mobile skin and it failed:

Does the propagation of the new IP take some time for some?

Interestingly, when insaw the above screen, then hit full site login, then tried to login, it gave me the old note above too. I am here now via cell 4G network iPhone 4S iOS 5, but I was in on wifi maybe 10 mins ago....odd? Propagation of new IP latency or something like that?
