Data pricing plans look to hold steady for the iPhone 3G and iPhone 3G S handsets in the near future per an article in the Wall Street Journal. “We’ve been very happy with our pricing,” said AT&T spokesman Mark Segal, who went on to mention the average monthly bill for an iPhone user was within US$90 to US$100. The article went on to suggest that AT&T could charge an additional US$10 to US$40 per month for MMS and tethering featured on the new iPhone 3G S. AT&T is currently facing pressure to offer lower priced data plans by both consumers facing the financial crunch and competitors setting aggressive data pricing.
