wififofum works dandy for me. no compatability issues with the custom 6.5.3 roms either.

has signal strength, channel, and all the other fixins.
And ... just for you guys ... I checked the gps compatability (never tried before on the tp2) and it works like a champ. So enjoy the GPS enabled wardriving should you have the need.
I like the radar view ...
