Re: In the us only tmobile or att works with the sim based iphon 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. |

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. |

Wind Mobile up in canada (nationwide 3g) will be AWS. If they want an iphone and TMO wants an iphone, apple may be more likely to make an AWS version of the iphone. |

China Unicom has GSM 900 and UMTS/HSPA 2100, and had already ordered 5 million iPhones for sale.

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. |
