I just have my 8320 for a couple of days and was only getting lower case uma or edge. Finally, yesterday I called back T-Mo and their PDA support told me that to get upper case UMA, I need to add an optional feature call BB Feature Enabler(Free). After I added that for free, UMA has been fantastic on my 8320 ever since. If anyone runs into same problem w/ uma only then try this and confirm.

Do you have a BB data plan or are you using th 8320 without a data plan?

I have noticed a few times my UMA has gone haywire and dropped it's wifi connection. When it's done that it will hook back up to EDGE, but it always stays lowercase and does not get data coverage. Sometimes the UMA will come back upper case or lower case.

The only way to remedy the problem for me is to power down and pull the battery, even a Cap+Alt+Del doesn't bring the radio back.

To fixed that problem. Turn off wifi and then the GSM radio, wait a few secs, then just turn on the GSM connection then turn on the wifi connection. I think that the UMA and EDGE are trying to request BB services at the same time and takes a long time for the BB servers to realize its two different request and to choose the right one to connect to.....
It should choose exactly what your connection preference is but TMO has yet to work the bugs out on that

I can confirm this... I recently had to cancel my data plan (long story) and I called T-Mo BB support... They added this feature and walla.... Uppercase UMA ect and yes it is a free addon.... It only allows you the ability to connect with uppercase UMA to your home router but it's what I needed at this point!

Thanks BBFan11!

One problem you may not have noticed is weather or not you tried to make a call with UMA on your bluetooth. If you do so you call will most likly drop, weather in a Hotspot or in a wifi area. I have tested it with several T-Mobile Curves and they all have the same result. While in UMA no bluetooth will work. I have tried it with three diffrent bluetooth devices from diffrent companies and same result. Sounds like a software glitch

I don't think it's a software glitch, though maybe. It seems as though the frequencies conflict.

Hopefully all the issues with the 8320 people have been experiencing will be fixed in the coming weeks. Or I might cry.

Nothing happens that quick. The 8830's and first 8300's had major calendar sync issues and it took quite a while for them to get fixed.

I just installed the new Yahoo! Go for the 8320 a few days ago. Everything was working fine until I go a connection error e33 in Yahoo! Go. After uninstalling and re-installing Go about 10 times I noticed that it finally worked when the 8320 was in the lower case uma mode. Once it changed to the upper case UMA the Yahoo! Go failed to connect. I wrote a letter to Yahoo to see if they know anything. I just decided to uninstall Yahoo! Go until I hear something to resolve this issue. When it worked it was pretty cool.

Yes. I have the BB data plan. I just confirmed my suspicion. My blackberry has been on the lower case uma for the last hour so I just re-installed Yahoo! Go with no problem Everything work. I'm sure now that if and when it switches back to the upper case UMA that Yahoo! Go will again fail to connect.

But having wap.voicestream.com in the apn field under Options >Advanced Options >TCP should help.

Leave the username and password blank.

Then reboot the device and try it again.

well....I've been on the lower case uma most of the day and all is working fine with Yahoo! Go. Yes.. the apn is set correctly with wap.voicestream.com only. Yahoo! Go is not an instant messenger..not sure if that's what you mean by IM client. Rather Yahoo! Go brings together various yahoo services such as maps, email, news, weather, and flickr...sort of like live search.

I had the exact same problem when I first got my curve the day they came out. Only lowercase uma/edge. I had to call T-mo and they told me that they should have activated this (free feature enablber) for me. They did it, and I pulled the battery, rebooted, and got uppercase EDGE/UMA.

edit

I must admit the sgt was/is correct. I have the data plan and I have the APN set correctly. The issue I was having earlier seems to be tied to Yahoo! Go only. It clears up after a while (referring to the connection error "e33). When my phone goes to lower case edge/gprs/uma I just go to the my-t-mobile site and refresh the service books and my upper case EDGE/GPRS/UMA returns. But when yahoo! Go works, it connects wether I have upper case or lower case.

edit

I'm getting this same error with Yahoo Go as of today. Yesterday it was working fine and today error e33. There's something blocking the connection to Yahoo. Everything else such as Opera browser works fine. Did a battery pull and nothing changed. I changed nothing in any settings at all. The only thing that happened between yesterday and today is auto off for 7 hours.
