I found 3 pads on the back that were not listed on @fanoush's Magic3 pin table: D13 (unmarked, grouped with SXD,TXD,D+,D-), D28 (unmarked, to the far right of that cluster), and D27 (unmarked, to the near right, below and to the left of D28). I also reused I2C SDA/SCL as I have removed the touchscreen. Of course, that's the ACCEL lines as well, so you'd have to write a cooperative routine that makes sure they don't interfere with each other.
Also good for hacking is the DT28 (also cheap on AE). No "new" pins that I found, but you can find the touchscreen pads (SDA,SCL,INT,RST). When I get a chance I can check the RX/TX to see what they are...
