Bare with me....I'm new to the cellphone forums.
But I saw your conversation and decided to create an account to tell you that I had the same experience this morning also. I am on my fourth phone from Best Buy, this is the second time this has happened out of the four phones.
I tried to do a soft reset...nothing...finally pulled the battery out..nothing...installed battery back in and reconnected it to charger and I believe another soft reset when it finally rebooted. Today is my last day before the 30 day return policy expires.
I'm not sure I should try to swap it out after reading a ton of other issues people were having with their phones. I don't want to go back to my 700wx and haven't seen another phone I'm interested in at this time.
Decisions....decisions...
