I have been using an unlocked 8300 on Tmo since it was released for ATT. Thinking about getting the 8320. Don't know if I'll use UMA, except when traveling internationally. I might, or I might not. Otherwise, (and I know its subjective) is it really worth spending the dough? Has anyone whose upgraded really seen a difference between the stability, functionality, etc, or is it all about having the WIFI?

If you are happy with your 8300, and are having no issues, and WiFi is not important to you... I don't see much you would be gaining.

Correct. I gotta say though, with WiFi calling, I'm using my 8320 as my home phone now and every chance I get outside my house. At friends houses, the first thing I do is get on their router.

Alot of folks are love ol' Uma!

In my case, I would not gain much with WiFi (that I can see, yet). Maybe I would and i am just too blind to see it.

Silverman--have you consiered the 8310 with GPS (rather than WiFi)?

Sanders, I have not considered the 8310. No need for GPS. I have one in my car, and if I am walking around and am that lost, I have bigger issues than a GPS will solve. Also, paying up for an unlocked model vs, upgrade price from Tmo would definitely cause me to stay with the 8300 until the next major release (9xxx).

Thanks for the insight.

WiFi/UMA that's all I have to say

yes it is worth it. I just came from an 8800. Can't live without the wifi. The difference is night and day.

Hey, folks. Other than the At Home feature, is there any difference in the Wi-Fi service/capability between AT&T and T-Mobile? The local salespeople are not able to answer this.

I didn't think AT&T had wifi or UMA?

I have the 8320 from TMO and now I can't live with out it. When I am in public I am alway scanning for free WIFI and going into Starbucks is a plus with their HotSpots!

The 8820 has Wi-Fi capability. I was trying to learn if it was any different from what you get with T-mobile...or if AT&T had crippled the feature as Verizon did with their GPS.

AT&T has not crippled the WiFi on the 8820, so if you can connect to a hotspot you should be good to go!

Yes it is worth upgrading for. WIFI is a really good feature IMHO.
