Just a warning: If you mess around with ANY of this and:

a) don't have specific written permission from the FCC or Industry Canada (or your local spectrum regulator)

and/or

b) Don't do it in a good quality faraday cage

You deserve an FCC party van...

Can you change the transmission bands to the ISM ones or is it fixed to GSM bands? For a tinkers setup, the frequency shouldn't matter since you may not care about performance? Asking out of curiosity.
I suppose you could, on the SDR, but then no standard feature phone or smartphone would talk to it.
