[andersondepaula]

Hi, my SX 56 (PW10B1) isn't working on Brazil because the GSM net is 900/1800. It's possible to make any think to change this reality?

Say, any version of pda softwares or another creator can change 900/1900 to 900/1800 or 900? I saw this kind of software on NET but isn't working properly (BANDSWITCH - XDA developers). This is a a beta version and dont work. Anyone knows any good software for this? If i upgrade system it can be works? can i get a better version of O.S for my SX 56 for free? Sorry for my poor english.

900/1900 is a hardware limitation of the device.
You can´t make the device to work properly on 900/1800.
You just can try setting it to GSM 900.

You can do this in the bootloader.
Enter bootloader, press the calendar button and select GSM 900

But pay attention entering the bootloader is the same a a hard reset. All your data will be lost....
