I have been avoiding the update messages because I feared my root could not be restored but now that I see that the z4root will still root the 340 update the update nags have stopped. Is there a way to manually get a update nag or to get the 340 update and do it manually?
Yes, if your allready on .320 then you need to flash the .340 system sbf that's out because thats all the the .340 update changes. You can find out more on mydroidworld.com you will just have to search. Just remembered I can't post links to sbf's.
If your not allready a member of MDW then I suggest you become one because there is sooo much DX info over there.
EDIT: cpjr makes a good point below, My post is not fully correct.
