All good so far. updates working ok. no issue with sudo files. just tried iPlayer and a combination of the speedpatch, and pretending I am using an iphone(using hide user agent) makes videos run smoothly again. Was very jumpy before applying these patches. Battery may even be better I think, as I have been using constantly and it's hardly gone down this time.

PS. If anyone didn't know about that trick. The best results from iPlayer I find is to just type "iphone" into hide user agent. videos run really well then. when you are done watching you can always put it back to whatever you want.
