It can't be set to 256 because it's only 8 bits.

(Edit: on reflection, if you know enough to know about the forwarding chains, I'm sure you know that TTL is 8 bits. Sorry.)

My bad, I probably didn't explain myself correctly.

I was talking about modifying TTL of the forwarded packets on the phone, to make the packets look like they were originated from the phone itself.

OK, yeah. I don't know how MyWi works; if it forwards everything by hand, then it can definitely do that. If not, yeah, it's dependent on what the kernel can do.
