I have flashed other devices, mainly froyo to gingerbread, and have been able to maintain apps and such. Honeycomb may a different animal, and I wouldn't be surprised if we had to reload everything after the update.
I think I was a bit hasty saying it was glitchy, I was being impatient, so don't worry too much.
Well done Dell! updated by October as promised earlier this week... Just!!
Good for you folks across the pond! Now for us here on the mother ship. I've seen the previews and it looks awesome! It looks like it'll do for the tablet what gingerbread did for my G2.
If you have the official over the air update maybe you would like to dump the open source part of your dell honeycomb update (aka a rom dump) over @ xda forums 😉
If ya can, they will tell you about how...
