difference between wallaby ver.?

[john]

Whats's the difference between the wallaby versions 5.15 or 5.17 etc...?
and if i own a us mda, what effect does it have to choose in bootloader mode the 900/1800 ?

[Peter Poelman]

900/1800 would mean you get no signal in the US, since providers there use the 1900 MHz band.

The bootloaders are pretty much the same, except 5.17 has some kind of silly protection built-in. See http://xda-developers.com/XDArit for technical details.

but CAN i change the frequency with thes bootloader? will it work then on 900 AND 1800? instead of 1900...
