Woke up this morning to this message: "Could not activate cellular data network. You are not subscribed to a cellular data service." I am using a BlackBerry Data Plan. Has anyone been successful reactivating the network on iPhone 3G firmware 3.1? Could they be so kind to share the process? I found this link below that indicates APN changes, however I'm not sure if this work with iPhone 3.1 (or if I need to downgrade to 3.0). http://limitededitioniphone.com/iph...one-data-plan-yeah-right-ive-got-you-covered/ Thank you.
