Absolute what radio would you suggest, my radio mostly holds steady after 5 min after turning on, but if I use the browser it drops to edge automatically like there is a leak of some sort. It is frustrating.
The problem is that past .90 radio code, most do not hold a steady EDGE connection. I would suggest installing the .90 radio code and I think you will find your issues resolved. Let us know if you need any further help.
should probably do what jlevy said, trying the .90 radio
