I enjoyed having MyWi on my jailbroken 3GS (with Spirit) and was lucky to pick up the Handy Light tethering app a few days ago but today decided to just bust it out and get the tethering package with AT&T. Handy Light is a bit of a hassle to constantly be setting up every time I wanted to connect and sometimes it just wouldn't work at all. The AT&T store rep pulled up my account and was able to see that I've used less than 1GB of data over the last few months- many times, much less, so having a 2GB cap won't bother me. The ease now of simply turning the tethering feature on via my iPhone and having it simply work is worth the extra $15. a month. For those who are using this service, do you recommend tethering via the USB cable or bluetooth? I tried the bluetooth and it seems to work well but am open to suggestions. Before I get the "cool story bro" I know my thread won't mean much to many but honestly, if you're on the fence it is worth checking out. If you're not using tons of data I can't see the disadvantage of 'downgrading' from unlimited to 2GB and the extra fee for tethering might be worth it to you.
