Ok, I got the same problem as this guy http://androidforums.com/htc-hero/7174-hero-orange-not-letting-me-sign-google-account.html But normally everything should work on my simcard.... Now the other part...Im from Belgium. The htc hero is not launched yet in Belgium because they need to remove the youtube app. So I went to netherland and bought a htc hero! Hehe...but then I tried to connect to the market...so I tried to connect to my gmail account and I got the same error as the guy above...From the simcard/service etc... Now I called my provider..he sais my simcard is quite new...so normally their shouldn't be any problem. I don't got data activated yet...but I'm connected true wifi...so that shouldn't be the problem? To be sure I activated the service right now..and waiting to get activated... Could It be that my htc is blocked because I'm using one from the netherlands in Belgium?because of the situation with the belgium htc's?? edit : tried to connect my hotmail account...this worked... edit2 : tried to connect to gmail manually (true email apps, and then configure) this works..tested sending emails etc..
