I’m not enabling tethering on my iPhone for two main reasons:
- I already have a Verizon USB EVDO card, and it’s a ton faster. If you need to use tethering frequently in the U.S., eat the cost and get one of these.
- AT&T’s network is complete garbage for high-speed data in nearly every crowded metro area, especially New York. Semaphore flags would be faster with less packet loss.
Tethering on AT&T isn’t worth the effort if you actually need to use the connection regularly.
