The one thing that I really think makes people jailbreak to tether is the fact that as far as I know, if you add tethering, AT&T considers it a change to your data plan & you will lose your unlimited data palm, which is not an option for me and many others. I pay AT&T $90 a month for data, I'll do what I want with it. I have unlimited plans on my iPhone 4 & my wifes as well as on my 3G iPad, so I should pay them 60 more, & lose my data plan... No thank you... Just saying... They are entitled to make money, yes.... But enough is enough...
This is very true. When I get an iPhone 4 in November, no way in hell am I paying an extra charge to share the same amount of data as if I wasn't tethering. No, AT&T, suck my balls.
