I just wanted to update this thread on the status of my device since loading the latest OS 6 v 188.8.131.524 a couple of days ago. The install was flawless and my device is running smoothly. I believe the random reboots are a thing of the past.
First, if you have waited to upgrade your Bold's software, go ahead and do so. This is a very stable software release. The reboots never occurred and a breath of fresh air was breathed into my device. It runs smoothly and snappier since the upgrade. I maintain a constant 3G signal with no dropped calls. The native browser works nicely, however, I do use the latest Opera Mini Version 6 Update 1 on my Bold. I prefer the Opera Mini browser just because it loads pages faster. Other features include an updated calendar and of course the new OS 6 interface. I realize some of you may not care for the OS 6 interface and prefer the old OS 5, so to you I say, stay with what works for you. My battery drain is minimal, no more than with the last OS 5 software release. As a matter of fact, I went to work last night with a fully charged device and came home with about 75% remaining on my battery. I did not make many calls last night, but I did answer a few emails and surfed the web a bit.
In summary, I am going to mark this thread as having a solution found. I firmly believe the first OS 6 release from Verizon had a poorly written radio file, thus causing my device to lose connectivity with the network and causing the random reboots. This was resolved with the .524 OS release. I hope this thread helps some of you who had the same problems. Gracias.
