4.1.999 gallery+themed google apps issues

---

gallery:
when i go to veiw a picture(meaning im looking at the picture) it wont rotate. bkmo said the problem was the stericson lockscreen. because when he put back the stock lockscreen it rotated again. so i think the solution there. but since the viewing isnt that big of a deal to me, plus i love the stericson lockscreen, im gonna keep my lockscreen so this is more for people wondering about the same problem...

google apps and themes:
if you flash a theme that modifies the google apps, flashing 4.1.999(and up) wont restore the stock app. clearly its cause he doesnt have the copies of the apps in there anymore. how do you restore? im not sure. i flashed a theme that themed my market red and black, then flashed his rom, then another theme, but the market stayed the same. im guessing that flashing the htc recovery, then the rom, will probably restore the google apps to stock, but im not sure if it requires a wipe.

does it?

because if it does ill just keep the themed market. its not really a problem, im just a little annoyed since im not sure if this has any negative effects. can anyone help on this? i dont wanna try because if i need to wipe, i dont have time to set everything up again. and i dont want to find out i did need to wipe and end up with having to wipe anyway. plus someone told me its possible to lose root somehow, and i only have 1 phone. otherwise i'd try this out myself for you guys. please someone try, or give some professional input on this. thanks!
