does iphone 3g work on tmobile?

[orangekid]

I heard a rumor that Tmo's 3G bands don't support the iphone, or the other way around. basically that the iphone 3G can only pick up ATTs 3g bands (like the nexus one can't get 3G on att) so you would be basically just as well off with a 2g iphone on tmo.

is this true? Does anyone rock an iphone 3g on tmo and can confirm or deny this?

That is BS, you can use a 3G/3GS on t-mobile IF you are jailbroken AND unlocked. You might not be able to use 3G HOWEVER you will be able to use EDGE.

In short NO 3G service on iPhone.

"3G (UMTS/HSPA/HSPA+) service by T-Mobile exclusively uses the AWS 1700/2100 MHz frequency-band, making it incompatible with other existing 3G UMTS/HSPA networks already established in the United States."

No, a 3GS on T-mobile will only be able to access EDGE frequencies but will only do so if you have it unlocked/jailbroken.

The 3G/3GS iPhone will be able to work on T-mobile's 3G network as long as it's NOT IN THE U.S! T-mobile's U.S. network uses a specific band of 1700mhz for upload and 2100mhz download bands. You have to have both 1700 AND 2100 bands for 3G speeds on T-mobile's U.S. network.

The iPhone Specs. are:
Quad band GSM 850 900 1800 1900 MHz GPRS/EDGE[14]
3G also includes: A-GPS; Tri band UMTS/HSDPA 850, 1900, 2100 MHz[15]
3GS also supports: 7.2 Mbps HSDPA

As you can see the iPhone DOES have the 2100MHZ band HOWEVER does NOT have the 1700MHZ band that is also required. However overseas the standard is quite different.

I know it's stupid and to tell the truth every company in the U.S. should upgrade to standard European 3G bands...it would make everyone's day a little better!!!!
