I used BlackRa1n today, and everything went fine, and now my iPhone 3Gs is working on T-mobile's network.
But my WiFi, and "Edge" no longer work.
I get this message, "Could not activate cellular data network You are not subscribed to a cellular data service."
I've disabled my 3G already... And have called T-Mobile about setting it up with their network. They informed me that it would take up 48 hrs to have my data service again.
Is this true? Is there any way around this wait? I can't even access my WiFi...
