As we now know, using Sym DR's latest revision, one cannot type an APN in the phone setup feature when programming a GSM iPack3. When not using Wind Linx, our GSM ipacks, version 36 and above, cannot seem to gain access to our ISP without an APN name. Our SIM card activations do not require a PIN. We received IE 075 and IE 082 in attempts to make calls. The latest SDR version works great with Wind Linx, but I was only able to successfully call with an older SDR version that I happened to still have (5.10.01). Any thoughts?
