It seems that when the iPhone's WiFi is turned on and the screen shuts off, the WiFi does too. When I first jailbroke my Phone, I found this incredibly annoying, because the SSH connection would keep breaking every 60 secs unless I touched the phone every once in a while. Is there an app, or better yet, an SBSetting plugin, that will keep the screen from locking, or just keep the WiFi connected?
