Same problem here, thank you guys for the Handcent blacklist fix. That's easy enough for me and I don't really care about VZW's feature, and permission, and them monitoring/having access and all that part of it.
Just wanted to say, I just quit working at a corporate retail store for VZW last week (to have a baby) and I sent this thread to a super techy friend of mine who still works at my store, as I'm sure he has or will run into this problem. Every little detail and problem of every phone and OS and how to solve each one is definitely not communicated to the retail, customer service, or tech support staff (that would be a ridiculously mind-boggling task), so I figured I would give him and the rest of my store a leg up with helping their customers on this issue.
I am a little surprised that a previous poster went into a store and they just told him to google it. Okay, yeah, sometimes we *think* that (obviously I just googled it without talking to VZW first and it was way easier), but really that rep should have googled it for the customer and then helped them out with either blacklisting on Handcent or removing and manually re-adding the email accounts as outlined in this thread. I just wanted to say, please be nice to your reps - we're just like you, working for a living, and we are really the lowest little bugs on the chain at VZW. We hate that they don't give us enough knowledge to fully do our jobs sometimes, and we hate that we have to implement customer un-friendly policies and do so with a cheesy smile and offer to sell you something. If only they didn't pay so much and have great benefits. But oh well, that's all over for me now.
Anyways, long winded, but thanks again for figuring this out for those of us googling after you!
