Engadget has a source telling them that Verizon will be removing their unlimited data plans, like AT&T did not so long ago, in favor of a "tiered bucket strategy" around the end of the month, possibly on July 29th. The two companies, as Engadget writes, are competitors, and they "tend to follow each others' moves pretty closely."
AndroidandMe adds that "Verizon recently updated their MyVerizon Android application with new features, like the ability to monitor data usage. The only real question left: how much will the new plans cost?"
However, Engadget mentions (and I agree) that the pricing strategies will likely be very similar to each other. AndroidandMe notes that "AT&T now offers two levels of data plans ($25 for 2 GB, $15 for 200 MB)."
Another lingering question in my mind is whether Verizon will allow customers already on unlimited data plans to be grandfathered in and continue to pay the same rate, or whether those customers will have to choose a different data plan.
