[Sorry if this a FAQ and answered elsewhere already.] I had talked myself out of exchanging my wifi model for the 3G...then it occurred to me that if I could provide a wifi to my wifes itouch, that would be really cool. I have been looking at the personal wifi units...but if the extra $30 was enough to sway me away from the ipad 3G...I definitely don't want to do $60 a month. If it's not possible now...is it ever possible for the iPad 3G to share it's signal? Thanks!
