I'm glad I found this forum. I've had the Reverb for only 10 days now and for the last 2 days there has been several times where my phone appeared to be stuck in a boot cycle. Usually, I would just see the "Samsung" text appearing/disappearing. Perhaps my phone also has a sticky power button.
Now that I know what is probably causing the problem, I'll see if I can live with the flaw and fix it as needed. Besides this one annoying problem, the Reverb is an awesome phone.
