Sold iPad 2.... buyer has 3g Issue

So... I had an iPad 2 that sold on e-Bay last week. It is not the first iPad that I sold through e-Bay (Original Gen. Sold Too), but was the first with 3G.

So I did the traditional wipe of the device. Before resetting the other options in settings. The 3G was deactivated about a month prior to selling, and account deleted.

The buyer receives the iPad today, and claims that she can't activate the 3G and needs my log-in credentials to delete my VZW info, and create her own.

I attempted to view my VZW account through their website, but they had both the number and the e-mail it was associated with as no longer registered with Verizon.

Anybody have a similar issue? Was it my fault? Or is it free from my fault?

Yeah CDMA is pretty much the greatest thing ever....

However, I do love that I still have my unlimited data for the iPhone. So its a love-hate type relationship I suppose.

Resolved!

I got the issue all cleared up. Apparently, I canceled my autopay, but did not delete my account profile. I clicked delete later rather than delete now since I had data left. (oops.)

I went to my local Verizon, the rep called Verizon Pre-Paid Customer Service, they verified my account information and deleted the account.

A power cycle by the buyer allowed her to get her account information up and running!

Thanks for the help!
