Bug 1093533 - Unable to install marketplace update on Mulet, system thin...

...k it is offline
this will not actually enable us to update app from the mulet right?

Can we reach this point in any on device cases? Looks like we early return if offline, and if we have wifi before reaching this. So we know we have no wifi, no mobile connection but that we're online.

Maybe we should  make _wifiAvailable() return true in this case?
