Looks like anyone who was able to keep their unlimited data from Verizon during a recent upgrade won't have it taken away now that the loophole has been closed. Here's the statement, via Android Central:
Over the past weekend, there was a software issue involving some orders for customers seeking to upgrade their devices. A number of customers who were upgrading devices were able to maintain an unlimited monthly data feature while paying a subsidized price.
Verizon Wireless will honor those orders that were approved this past weekend, allowing those customers to retain their unlimited plans for the duration of their contract and receive their new device.
Verizon Wireless corrected this software issue today (9/30). The company no longer offers unlimited data plans and customers who want to retain existing unlimited data plans, must pay full retail price for a replacement phone.
So not a pardon, but a stay of execution. They'll likely get that unlimited data plan from anyone who's still holding on to it, it just won't be this day. If you managed to keep yours, let us know!
