Re: In the us only tmobile or att works with the sim based iphon said by jvanbrecht:The major issue with Tmo 3g, it runs on an odd frequency band in the US. So apple would have to make a separate device just to work on Tmobile in the US. Also, in the end, LTE has a much higher bandwidth rate (if memory serves me, up to about 300ish mbit down, 100ish mbit up), UMTS will never reach those speeds. Maybe, maybe not, a firmware change for T-mobile might be all thats needed. And I think they are having to some funky thing with the iPhone in china to get it to work on there 3G but i'm not 100% sure on that.
LTE does have a much higher bandwidth rate then HSPA, but the question is, how fast are carries going to let it get there.
Verizon said 6 - 8 Mbps at LTE launch, are they going to keep it that speed for 5 years? no one knows, Going by what T-Mobile said, there 3G will be faster then Verizons LTE, at least for a little bit. | |

I wouldn't expect any CDMA 1x/EVDO chipset in the near future, unless the CDG paid for it (not likely)
Stats: GSM / HSPA = 89%, CDMA 1x/EVDO = 9%

GSM base added more customers in the last year than CDMA has total. | |

To work with T-Mobile's 3G, a new radio would have to be installed, but that wouldn't be that hard.

A firmware change will do nothing, the radio unit inside the iphone is a hardware unit that only supports specific frequency ranges. For 3g to work on Tmobile, it would require a completely new radio. | |
