What's inside that Sara-R4 cellular modem module?

Ever wondered what’s under that shield in the Sara-R4 modules? After torturing mine with 3.3v applied to the wrong pins it seemed dead, so having not much to loose I popped off the shield. Turns out the module actually isn’t dead and now works fine, but hey, might as well snap a few photos in the meantime :-). It’s pretty darn tight in there!!
