Must have been nice.
I decided to jump through hoops and update my Dream that I haven't used in over 2 months, and even that was only for a day or two...and it was months prior to that that I had used it.
But I accidentally made the mistake of putting my SIM card in it to verify that it worked....I updated the phone, switched the SIM back to my Nexus One and went on my merry way. 2 hours later, no data. So I called and was told that the data was not turned off on my account. Thinking it was a bug in my Nexus on Rogers, I accepted that. Put the SIM back in the Dream, still no data. Talked to the Live Support person who then confirmed that it was disabled and then said there was nothing they could do.
So now I'm stuck with no data for the night. The worst part is that the guy was very condescending to me and that the other CSR lied to me when he said my data wasn't turned off.
And of course the Retention person that I talked to thought he was doing me an amazing favor by offering me a month credit on my data package....right at the top of the instructions says that it will be automatically given...yea, that's really a huge favor.
So, if you're not using your Dream and decide to update, don't put the SIM in...or if you want to use your Dream/Magic but haven't for a while, update first, then put your SIM card in. Hopefully you can avoid what I went through.
