I have a usb cable purchased at radio shack (futuredial). i didn't want to purchase the $40 software, so i tried downloading version 3.11 of the mobile data tool. i was successful in the download...but it won't see my phone (motorola v262). the cable i bought is compatible with earlier motorola phones, but there was not a listing for the v262 on the box. the phone beeps when the cable is connected, and it appears to fit. the MPT will not let me do any live update like i've read can be done to upgrade it. is it most likely the usb cable, the mpt or just general operator headspace and timing????? somebody help me!!!! please!!!!
