Use your Tritan as a modem.
These instructions are for US cellular, not sure about Alltel.
Make sure your data plan includes it.
Took this from another forum, tried it, works awesome!
Use your charger usb cable.

What if your plan does not include this?  The US Cellular rep told me you can't use the Tritan as a modem.  Can I just do it anyway?

Trying to run the software and it says it may not be compatible with Windows XP and I should stop installation.  Do you have XP?  Does it still work?

*Disclaimer*
Check with your provider before doing this, your plan may not include this.

Anyone use this with alltel? I can set it up but i know the phone number @uscc.net won't work. Any ideas will be appreciated.

How come listed saying if ur plan has it? u cant get a plan with tethering unless u have a blackberry or windows mobile plan! it works but if u use it enough they will catch on and cut u off!

I just did this and it works good. My phone says"Data Call" and shows the minutes am on the internet. Can someone tell me if this will block incoming calls and if this uses my calling minutes? I do have an unlimited internet plan with my phone.

Thanks

hey i tried it and it worked perfectly! i have alltel (now verizon) and i downloaded the driver restarted my computer and followed the steps of the tethering instructions for us cellular and it worked perfectly for me. i have windows vista and it works great! thanks!
