The older iPhones do not support the USA T-Mobile 3G network.

I have the t-mobile pay as you go plan and wanted a more updated phone than the clamshell motorola. I talked to someone at t-mobile who told me that the 3gs works with that SIM card, so I bought one (factory unlocked) off ebay and brought it to the store to get the SIM card installed. And, it WORKED! So, under some circumstances, iphones and t-mobile do connect!
