I had the old T-Mobile sim card in my 2G and was getting free data for about 1 year. 2 days ago I kept getting the "SEARCHING..." signal and "No service" signal. I swapped my wife's sim and her sim worked in my phone and my sim didn't work in her phone.
So I go to t-mobile store and get a new free Sim card, they are all 3G sims now. No more 2G sims available.
Now I can't get the free data anymore. I tried all the APNs and no luck. Shucks

Was the 2G Sim the loophole to get free data with internet2.voicestream.com?
Anyone else have this happen to them?
