Thinking of changing phones or signing up for TMO? We had to pay $50 in upgrade fees when we added two G1s in our house. You may be able to avoid that this Friday through Monday... T-Mobile Does Away With Activation and Upgrade Fees Posted on Feb 10, 09 09:32 AM PDT Sounds like a dream? Well, this dream won't last that long as it is valid from February 13th to 16th only, so if you're interested to fall under the umbrella of T-Mobile as the carrier of choice, those four days will see all activation fees and upgrade fees waived as long as they fall under the ‘qualified purchases’ category. There is still no exact definition on what a ‘qualified purchase’ is, so it is a good idea to check with your local T-Mobile store or give their representatives a call for futher information.
