Help with the frequency in Brazil ! - Sony Ericsson XPERIA X10 Mini

I need help, in Brazil, the frequency is 850/1900/2100MHz 3G and
[ROM] MiniCM7-2.1.9 [02/11/12] Gingerbread 2.3.7/CM7.2 does not allow to connect on 3G network in the frequency of 850 MHz EDGE only ...
This ROM works only on 900/2100 3G network ... someone could help?

Oi Cara,
What network are you using? Also, what model phone do you have? Mini pro, or regular mini?
I'm using claro, Vivo and Oi, no problems with 3G or normal on x10mini.
I'll test TIM with my wifes tomorrow and see if it's ok

I'm using the network vivo, my phone model is the x10 mini pro, what happens is, in my region the frequency is 850 MHz 3G, and it seems that the device only gets EDGE with this often when I switch city ​​where the 3G is 2100 mhz .. operate normally, the problem is this, but only 3G takes on the frequency 900/1900/2100, 3G does not work at 850 mhz

I only have an 10 mini (without keyboard) but just from looking at your phone specs, you might not be able to switch like this. You might be able to change your Build Prop file to change your phpne from an a model to an I model, or vice versa.
I'll try to dig up some more info!!
