I'm paying like $67/month now for bare essentials (including unlimited data) and that's about as low as I can get it without dropping the 1000 texts plan for no plan at all. I'm tempted by GoPhone, but I heard FaceTime and Visual Voicemail don't work unless you jailbreak. My phone is unlocked, but I also heard that AT&T gets angry if you use an iPhone on a prepaid plan and threatens to cut off service. Still, GoPhone is only $50/month for unlimited everything. Would be nice. Any experiences to share?
