Hi Guys, thought I'd post up my experiences, might help someone else..
I'm on my second tablet, the first one - when you turned on wifi it would come out with some weird crackling on the speakers, even when it wasnt using the sound. Sent it back, got a second one.. started doing the same thing!
Then I remembered back a few years when I was modding my hd2 phone - people had the same problems with the roms.. The answer is to turn off 'touch sounds' in the sound config menu. So no more click-click, but its sorted the feedback sound. (scroll people! - please fix this!)
IPlayer.. bit of a work around - and not a total fix.. download dolphin browser (you dont have to use it) - then the iplayer app.. use the app to pick what you want to watch, it will ask you what browser you want to play it in. (just select dolphin as the default). It will work.. and play.. but dont try to enlarge it to full screen, or it will crash the whole thing! (its still big enough to view comfortably tho).
Soooo.. with the market working, iplayer & my sound prob fixed (sorta) - I'm quite enjoying the experience.. just wish it wasnt fitted with the worlds smallest battery! (I get about 2 hours from a full charge.. gaming.. internet & kindle)
