People with update please post update results

Huge improvement in wifi, maybe a slight improvement in 3g according to before and after speed tests(wasn't a problem to begin with for me), My PRL and Profile will update which it didn't before, volume is louder (I no longer keep it on max). I never had a problem with calls dropping. Overall, a worthwhile update. Can't comment on 4G yet.
 
My 3G speeds are greatly improved overall. I hit over 2 Mbps and that has NEVER happened before. I see a lot more 3 and 4 bars everywhere I go, whereas before it would be 1 or 2, sometimes 3 and almost never 4. On average I am seeing 0.7 Mbps and above anywhere I am, even with places with low signal and before I'd say it was more 0.3 to 0.4 Mbps average pretty much everywhere. I rarely got up close to 1 Mbps, in fact I can only recall going slightly over 1 Mbps a couple times and those were in much more sparsely populated areas than where I usually am (Houston).

Glad to hear since at times my 3G would go to 1G
 
Wow amazing update. I was getting .4 Mbps down on 3g in my house. Now its a steady. 85 to 1.1. Wifi is slightly improved. And before on 4g I was getting 8-9 Mbps Max. Now I'm pretty steady at around 12-14 Mbps down and in real crappy areas the lowest is around 5. Speaker sounds clearer but I'm not sure. But, overall great update!
 
My results have been very positive. I am rooted and was running the stock kernal and stock GRJ22 firmware. I flashed the new GRJ90 firmware. I also flashed the new radio firmware D720SPRKE5. I do not have 4G in my area and really did not have any 3G problems before but I can safely say that my 3G signal has improved. At my home I went from -86 dBm to -75 dBm at my office I went from -115 dBm to -86 dBm. WiFi signal has also improved. Speeds have increased slightly but hard to measure the exact change due to the inaccurate nature of speed tests. Loosing wireless tether is a bummer. If my signal strength was not such an improvement then I would just flash back to GRJ22. Even still when I need wireless tether I can flash GRJ22 over my current ROM and have wireless tether up and running in about 3 minutes total. I can live with that.
