There are 4 test points accessible from the battery compartment under the SIM card slot. I shall number them as follows: B A (battery connector) T +-----+ | | | SIM | | | +-----+ 1 2 3 4 i.e., the test point closest to the headset jack shall be numbered 4. TP 1 and TP 2 have tiny vias inside the TP pads themselves; these vias appear to go no deeper than L2. TP 1: on L2 it crosses over the tiny via coming from L1 to a larger via that penetrates almost the entire layer stack. On L7 the latter via connects to a trace. The latter trace runs at normal signal thickness until it hits yet another via. On the other side of that via, still on the same L7, there is a dead-end arm of what appears to be the same net, and the latter arm is thick - almost as if it acts as an antenna of some kind. From there the connections are unclear, but it appears to connect a bunch of fat traces and possibly even copper fill on other layers, so it's unlikely to be an interesting signal. TP 2: on L2 it goes to a trace, that trace goes to another via at image coords (4378,1746). TP 3 connects to a via; that via appears to make a solid connection to the copper flood-fill on L6. TP 4 is connected to the L1 GND copper fill with thermals.
