Some friends at Jkkmobile have successfully added a 3G modem to the ASUS Eee PC T91. One of the tricky parts is actually opening up the laptop, since Asus didn’t include any access panels for accessing the storage or wireless modules on the base of the netbook. As a reminder, the ASUS Eee PC T91 is an 8.9-inch netbook with a swivel touchscreen display. The tablet is powered by a 1.33GHz Intel Atom Z520 processor, an Intel GMA 500 graphics, a 1024 x 600 touchscreen display, and a 802.11b/g/n WiFi module. Watch the video after the jump.
