Hi there, in the beginning I didn't think that I could need the WWAN / UMTS functionality for my new T5010. But now this changed - after upgrading my iphone 2G to a 3G model I now want to upgrade my tablet pc also. I'm located in Europe so my model isn't identically to the us version. A) Which WWAN card for EU model - MC8790 First question was: Which module I need to buy for having WWAN functionality. I found out that Fujitsu uses the Sierra Wireless MC8790 3G module in Europe (=86&tx_ttproducts_pi1[product]=5161]tech specs). I costs about 180 EUR which isn't cheap but that's the deal Additional tech specs: http://www.sierrawireless.com/product/mc8790.aspx B) T5010 opened - everything seems prepared for WWAN Today I opened my T5010 using this great tutorial . Here's how it looks: It seems that everything is prepared for this card (cables, connections, etc). I just have to buy the proper WWAN card and connect it correctly. What do you think? Is this as easy as it seems? Thanks for your feedback and help!
