Can't download apps or access network

[PhilsGhost]

I just got my Galaxy Nexus today, but whenever I try to download an app, I get the message "_____ could not be downloaded due to an error".

Furthermore, even though I'm on a data plan, I don't appear to be able to access my network (Rogers, btw) I can only use data when there's a wi-fi network available.

Anyone know what might be going on? Any help would be appreciated.

Did you buy the phone from the carrier or an importer?

Have you tried other SIM cards? Have you checked your APN settings?

Bought from the carrier. Haven't had the opportunity to use another SIM card.

Changed to the correct APN settings (thanks for reminding me, should have been the first thing to do lol) that fixed the network problem, but I still can't download anything
