Flash T-Mo 8320 w/AT&T SW?

My wife is running my old T-Mo 8320 on AT&T wit no data plan and it's working for texting and games great. However, the WiFi indicator won't ever show connected because it can't establish a UMA connection. If I flash AT&T SW on it, will that correct this issue, as well as get rid off all the little "@T" symbold that showed up on it when it connected to AT&T?

Thanks!

I do not believe that AT&T has UMA.

Also, if she started using the device after September 2009, AT&T will likely automatically add a data plan.

She's been using it for 6 months with no data plan added. She's out of contract so if they do I'll tell them where they can go.

I know it doesn't have UMA, but I want the Wifi indicator to light up when it has a valid WiFi signal. As it is now, under the T-Mo SW it won't light up unless it has a UMA connection which, obviously, isn't possible.

You cannot remove the TMobile branding (at least not legally).

Have you checked out the WiFi guide in the "How To" forum?

The WiFi works great. I just can't get the frackin' WiFi logo to light up because the handset is trying to establish a UMA connection. :(
