I know there's some argument in the other zv9 threads about whether the radio update helps. I internally debated at length about whether I wanted to take the risk of potentially making things worse (VM did pull the update after all), but after reading through all the threads I could find across all our OV forums, I figured I'd take the plunge and worst case I'd hope it wasn't too hard to get my old firmware back.
So I can't speak for anyone else, and obviously conditions will vary depending on your location, cell coverage, OV model, etc., but here's my experience:
My speedtest bandwidth results are 5-10 times faster than they were prior to the update. I get the same results on stock, CM7, and CM9. The following numbers are approximate, but I'll see if I can also get a speedtest with my new results posted.
Before: 200kbps down, 50kbps up - these are the fastest speeds I ever saw, in any location, under any conditions, even metropolitan areas blanketed in 3g coverage. To be fair though, I got those speeds relatively consistently.
After: My very first speedtest (on froyo stock) after flashing the new radio was 1000kbps down, 250kbps up. I've since seen 1750kbps down, 800kbps up in my best test - and I got several test results in a row in that spot ~1500/500kbps down/up.
Signal strength seems slightly better, but I don't have detailed records to compare with my current performance. Similarly, GPS lock seems quicker, but this could entirely be placebo effect. It has *not* helped my pings. The bandwidth though... not placebo. Those numbers don't lie. The radio update gave me a dramatic performance increase for relatively little hassle.
My max speed is always 200kbps with metropcs on my OM and OV, I'm gonna try the radio update with my OV (which is on metropcs) and I'll see what my new speeds are ^_^
Also there is a way to revert back to ZV5 now, just look in Petrah's last post or the end of the OP.
