they seem to use lead-free solder in the original construction process. goody for the environment, but it made it really hard to get the original battery loose. i added a little bit of regular solder to what was already there and then was able to wick away the original.
ugh. i totally mangled my case. snapped off the 2 outer screw brackets... broke my dental pick, too. and my small screwdriver. thank goodness for craftsman tools! ;)
i was pretty disheartened by the whole thing, but i keep it in a hard shell anyway so it's not that noticeable.
