There’s a rumor swirling around that AT&T will finally allow tethering on the iPhone in September and will cost $55 per month. AT&T has delayed the launch of tethering after Apple’s 3.0 release but hadn’t given any word besides later “in the summer”.

Hopefully the cost of the tethering would be lowered but knowing AT&T, they’d probably want to squeeze every dime out of iPhone customers. Many were hoping AT&T would charge around 30-40 dollars for the tethering service but based on rumors on Crunchgear, it may be around $55. Good Luck If you’re an iPhone Customer, that’s another $40-$55 dollars tacked on to your already high monthly bill.
