Hi. I have a Pantech UML290 USB on windows 7 64 bit. I just updated to the newest version of VZAM v7.6.4.4.2672s firmware L0290VWB522F.242 and no longer get a 4G connection. I uninstalled this version of VZAM and installed an older version I had archived (v7.6.3.5.2642k) and now I am back to my 4G connection. I cannot remember what version I had just previously to v7.6.4.4.2672s, so can you kindly tell me where I can get older versions of VZAM. It seems that at least for me v7.6.4.4.2672s is not working.
