wow, this is a great forum. After research on here, I am selling my 16gb, xp system on ebey now, and I haveordered another with the att WWan option. It should be here next week. Although i am an avid tinkerer and have solderinmg skills, i am going with the oem option of having dell's antenna, wwan port, etc.
I have since won a verizon USB720 card on ebay, actually i bid on 4 of them and forgot to cancel the others and won 3 of the 4! SO if you're a verizon customer waiting for someone in these forums to sort this out, it's gonna be me.
Once my new system arrives, I will be doing a thread on the exact steps to get this thing up and running with a verizon card, and will be selling my 2 extra USB720's also.
Thank you BombrMan, for your replies!
