Hi all, I have an unlocked iPhone that's working fine with my T-Mobile SIM card and blackberry data plan. Everything works fine, just that the speed is a little slow even though I put in the edge network settings and the Edge symbol does show. I called t-mobile to ask about whether or not I was incurring any data charges and they said no. I then asked about other data plans and told the guy why. He got very excited hearing I was using an iPhone on their network and recommended their "total internet package" to give me the best possible speeds. Anyone using this plan? Any problems? I don't want to 'break' my data capabilities by switching and was just looking to verify it works. Thanks.
