so the 668 is better than the 666?
I thought it was a little faster/smoother. Now there is v.706 from New Zealand. Now that OS is way faster/smoother. Better signal. I now get 3G at m home when the best I could get was EDGE. Check here.
Will that work on the bold 9780?
here for all the official OS downloads for your 9780. Also, when you decide which OS you want to upgrade to, read through one of the best How-To's around, here: All In One Guide - How To Upgrade Your Device - with Pictures & Videos
I have the v706 OS on my 9800 and I can tell you that it is by far the best upgrade yet. It is much faster when accessing anything on your phone and I now get 3G in my home when I only had EDGE for like ever.
You can read about the v706 OS upgrade that we did for the 9800 here. If you decide to upgrade to v706, make sure you read post #5 of the 9800 upgrade. For some reason, some people were having issues with a second vendor file that was hidden, but I was able to find it.
Anyway, what ever OS you decide to upgrade to, you won't be sorry as they are all good. Just post any questions you may have and we'll get you set up.
