Hey guys,

It seems whenever I connect to the internet, my N900 (apt?) automatically checks repositories for updates. This is great if I'm connected to a high-speed wifi connection, but on GPRS @ $2.05/MB, I "DO NOT WANT".
Every time I connect to a GPRS network, it uses at least a megabyte, which makes me hesitant to connect to the net at ALL. There's no setting in Application manager or the Settings menu, and after searching these forums I found something to change the check-update frequency but not disable it. In theory I could bump the UNIX time to a high value, but that's a hack.

Is there a way to disable update checking over GPRS, or at least temporarily disable it?
