Does this definitely work- can anyone else confirm before I buy this? And will the app still work if you put the iPhone to sleep as opposed to leaving the screen on?
UPDATE: I ended up purchasing the app and testing it- and it works!! Only downside is the screen has to be kept on to keep the tether active, but I kinda figured this would be the case. But for $2 compared to paying your carrier ~15 month it is totally worth it!!
Looks convoluted... glad I got iTether a while back when that happened. I think it was $10 or even $15 possibly, but it being super simple to do and you can sleep your phone while tethering made it an invaluable tool to have.
