It is my understanding that the 3g network coming out in the USA from T Mobile is WCDMA which is a duel band 1700/2100 system where as the European system is 1900/2100 meaning that the tri band phones ( my TYTN II ) will not work on this new 3g system. Is there any way to change my phone to 1700/2100 from 1900/2100. The duel bands are one for uploading to the tower and the other to download to the phone. In the USA the 1900 band is used for pda service thus T mobile is going with the 1700 band.
I am not in USA. I wanna know if Infuse support Band 2100 MHz(WCDMA)？Thanks！
Here's a link showing technical specs, including supported bands:

Isn't 2100mhz T-Mobile's AWS band?
Sent from my Samsung Infuse 4G
Yes, the Infuse 4G supports the 2100 MHz band. It is the band for international use.
On the other hand, the T-Mobile AWS band uses 1700 and 2100 MHz together, which does not apply to this phone.
yes, I have has mine run on 850, 1900, and 2100. dialpad *#0011# shows current freq
My question is.... can i use the 900mhz 3g band in the gx2???
sorry for my english
No you cannot. G2X is only dual band 3G. It can use AWS which is 1700 & 2100 and can also use band 1 (2100) by itself. It doesn't support any other 3G/4G bands.
Ok so I know verizon uses 800 and 1900MHz bands, as will sprint with LTE. However, Wikipedia says that the 800MHz band is reserved for iDEN devices only so how can verizon be using this as a cellular band?
Verizon uses the 700mhz band to my knowledge. 800mhz is owned by Sprint.
I'm confused on bands / frequency.
I thought each technology had their own specific band. For example LTE would operate on it's own band and HSPA would operate on a separate unique band.
However, I'm looking at frequencies now and I'm seeing the multiple technology operating on the same band. I don't understand that.
In example I'm seeing something like this
3G capabilities = 850, 900 MHz, PCS, IMT ,UMTS / HSPA+
3G capabilities = 850, AWS (Band IV), 1900, 2100 MHz, UMTS / HSPA+ / DC-HSPA+
I don't get how 3G has different bands. Also looking at the above, are they saying HSPA+ does not have a frequency? or that those listed frequencies can support HSPA+?

Bands are kind of like channels, different frequencies have different benefits.
http://en.m.wikipedia.org/wiki/Cellular_frequencies
The different technologies are not all deployed on one tower. What happens is tower a may use umts on 1900mhz where tower b across the state may only use pcs on that frequency.
Generally,
Lower frequency, more range and penetration through buildings and trees BUT less bandwidth.
Higher frequency less range and penetration through buildings and trees but higher bandwidth.
Now, with that being said what is done with the frequency with things like FDMA, TDMA, CDMA, and OFDMA can change how much is sent on the frequency and how many users can share a frequency.
The term waveform can be used to describe what is being done with the frequency much like AM vs FM.
That is the difference in 3G, 4G, and 5G. The technology on what the frequency is doing.
That is also why the higher the G the more battery is used. It takes more computing power to sperate your traffic from everyone else.
