Edit: I figured this part out... there is an option to lted, -n that lets you specify the profile number.
Thanks for this. Would you by chance know where the lted binary is built from ? I'm trying to get this device working with Verizon for internet access and also to be able to send and receive text messages. My understanding is that for this to work, vzwims has to be the APN in profile 1 and vzwinternet has to be in profile 3. lted seems to reconfigure profile 1. I can manually handle that, but I guess I'm trying to figure out how to get lted to use pdp context 3.
