I was having horrific problems with 3G cutting in and out, if you can call it that. To me it looked like the phone was failing to open the 3G data connection when it was needed by any application that uses data, taking so long to do so that the application would report "network problem" even in a good strong signal area. When the data connection would finally open, the data transmission speed was horrendous and the connection would drop in the middle of the session.
In researching the issue I found discussions on the DMU reset and the ESN swap fixes. The ESN swap fix is supposed to do the same thing as the DMU reset. The ESN swap is accomplished by the user on their account management web page - you just find another phone you can provision on your account by entering the new ESN or MEID and updating your account to use that phone, then, you repeat the process by putting the Fascinate ESN or MEID back in service. Verizon CS can also do it.
I was quite skeptical of this - the timing suggested that something wasn't right with my phone or my ComRom 1.3 installation, as opposed to a network problem, but I tried it anyway, and things are working much much better now. I'm always leery of placebo effect with "fixes" like this, but I think I can safely report that the 3G data connection is now established quickly when it is needed by a data application or the browser, and my speed tests, which were in the <100 kbps range in a good signal area yesterday, are now in the >300 kbps range in an area where there is barely enough signal to light up one bar (approx. -106 dBM). So for now, I think the ESN/MEID swap did the trick.
It was kind of old school to pull the old BB Storm 2 out though. Just for grins I put a charge on the battery so I could see what a seven minute boot looked like once again.
