re battery replacement "do not remove" sticker

hi there, just got around to replacing the 3 year old battery in my 3gs iphone. everything went as described in your instructions but i had to scrape off the "do not remove" sticker mentioned in #11 because it was stuck. by doing that i destroyed it and could NOT put it back into place.. now my concern: could something short circuit with that sticker no longer in place. should i reopen the phone and place some electrical tape over the 2 screws the sticker covered.

otherwise phone works fine.

thanks and regards
