if i did it good thats what it said.

~ $ "cat /etc/apt/sources.list.d/hildon-application-manager.list" http://repository.maemo.org/extras/
-sh: cat /etc/apt/sources.list.d/hildon-application-manager.list: not found

could it be firewall(router) problem? becouse i also cant retriving emails.

ok it's definitely router problem! whan i connect through my cell phone it's working great..
any idea's how make it work?
btw internet is working via wifi, only app manager and email doesnt work.

you have to type it without the quotes:

but if it is working with phone, problem is somewhere else

I have exactly the same problem but it isn't the router as it works perfectly with my desktop machine. I'm about to ditch the IT, personally since there looks to be no PIM with Win synching on the horizon and the email has always been flaky.
I've also been trying to find a serious French/English translation program like LinguaFranca for Palm/ Windows/ Mac but given up on that too. A few half-asssed things available but nothing up to a serious job.

It's a shame because I really like some aspects of the IT but it's really a little entertainment device rather than the serious Linux computer I'd hoped I could make it.
No criticism of the IT, just my( expensive:-( ) mistake.
