Just returned from a two week cruise to Norway starting from Rotterdam. Going through security was not a problem going,just told them I had a ipad in my carry-on in USA and Holland,returning was a different story with security at Detroit airport,told them about the ipad and it went through,then some eager AH made me take it out of the bag and made me go through again,telling me they had to check behind my case to see if I was hiding anything,I asked the guy what could I possibly hide behind the case that they could not find on the first screen check. He then asked me to empty everything from my pockets again,he even went through my bill-fold checking in-between the bills and credit cards and asking me did I have anything sharp in my bill-fold.I told him the only thing sharp was the edge of my credit card,that got me a rare look from the dummy and he then said "you are now clear"A real Dick Tracy showing off his power. As for my International 3G plan from AT&T it was a bust,as soon as I left Holland for Norway I had no signal and thats the way it was in every town I visited,the places were so barren, and no towers to be seen on the mountain tops, even the ships Wi-Fi was not much better, the laptop people were crying the blues because of no signal. So bottom line it cost me $14.95 for the the domestic plan (Which you must have before you can purchase the International Plan) which cost $24.95,so I paid $39.90 to carry a brick around with me.
