Apple iPhone 3GS
Using unlocked phone
I use a simple GMS (factory unlocked) Samsung phone now with an ATT Simm card (pay as you go).
Would like to consider an iPhone 3G and would use it mostly for GPS, photos, Wi-Fi.
If I get an unlocked 3G model can I simply insert my present or another ATT simm card? (I called ATT and was told I had to go to a store to find out).
Thanks in advance for your input!
