I am trying two sticks: http://www.ebay.com/itm/Qualcomm-3G-CDMA-model-GIO-225-T-Mobile-HU-locked-w… and http://www.ebay.com/itm/HSDPA-EDGE-7-2Mbps-Wireless-USB-3G-Network-Modem-Ad… I'll let y'all know how it goes. I'm curious if that diagnostic channel is available in other devices. I have a geeksphone keon that I sure would like to make more free... -Craig On Sunday, November 24, 2013 7:05 AM, Craig Comstock <craig_comstock(a)yahoo.com> wrote: Does anyone know if there are other models other than the Icon 225 that have this diagnostic mode? I just bought and Icon 225 via ebay but it is a CDMA version from Hungary. If all I can do is play around with the diagnostic mode that's fine but if another device would also work with GSM that would be more fun.
