I recently purchased the iPad 2 w/ wifi and I'm wondering if anyone has upgraded to the tethering plan offered by at&t? I have some questions for those who have: 1-I currently have unlimited data. Is it true if I add a tethering plan I will loose my unlimited data? 2-From the att side and the rep i spoke to said there's only a 4gig plan which is $45. No 2gig? 3-If I have a family plan do the others share the tether plan or is the tether plan specific to only one of the phone numbers? 4-Should i wait for OS4.3 to be jailbroken? Thanks in advance!
