Thanks to one of our trusty tipsters, looks like T-Mobile is changing things up a bit with the Partial Upgrade Pricing discounts. Beginning Friday January 29, T-Mobile will be offering two new partial discount options for existing customers when they upgrade their handset or device. Qualifying customers currently on a 2-year contract must upgrade to a new 2-year agreement and meet the Early Upgrade or Early Upgrade Plus requirements. There will be two tiers. Tier 1 is from 1 month to 11 months. Tier 2 which will offer the larger discounts is from 12 months to 21 months after the last upgrade. Stay tuned for more info and don’t forget to leave your thoughts in the comments!
