Engadget is reporting that Verizon is once again tweaking their 3G data plans, and this time it looks like it is in preparation for upcoming as-of-yet unannounced 4G LTE data plans. The $15/150MB per month for smartphones is no longer on the menu, leaving the unlimited data for $29.99 a month as the only option. Meanwhile, for $10 per month feature phone users can get 75MB of data, with a $10 overage charge scoring 75MB more if you happen to go over. The interesting thing in the fine print is that they specifically call out Feature Phones and 3G Devices. Does this mean we will have special pricing for 4G? If history is any indication, we may be paying more for LTE services.
