Tethering on ATT

[gregpilot]

greetings, everyone. I have been really happy with my Apache, tweaked of course. But it may be time to switch to a GSM carrier. I'm on verizon, and it seems in my local area the service seems overloaded, a lot of dropped calls, etc. Anyhow, I'm pretty familar with tethering issues with Verizon and the software needed to make it work...I am not trying to "steal" data, I cough up $$ for a plan. Using Wmodem, ICS, etc to do the tethering. I was wondering how these apps worked with ATT's network. It seems all the carriers are trying to push "laptop connect" cards and the like as a separate service plan but I feel that if I am paying for unlimited data it should not matter if the requests are coming from my phone or if my phone is merely a modem for my laptop. I'm using the network access I pay for in either case. I am not going to make the change if I can't tether without paying for two service plans. Anyone here have experience tethering on a WM 6.1 device on GSM????
