I've been using an ATT 8820 on T-mobile for months now, no problems. I noticed that T-mobile started selling the 8820 on Tuesday March 24. So I loaded their handheld OS, ver. 4.2.2.193. I have, what I believe to be, all the certificates installed for UMA, t-mobile_root, t-mobile_trustcert, us.tmobile.midp.SemiTrust, and us.tmobile.midp20.FullTrust. All are installed and have a green check mark. I only restored a minimum of apps, did a battery reset, reloaded service books, and thought UMA might work. Well, it doesn"t. I'm using WiFi at home WPA-Personal TKIP, and have no problems. Does anyone have any idea's as to what could be wrong? I would think that T-mobile, since they already know I have an 8820 from my pin number, would have turned on, in their service books or certificates, UMA for an 8820. They don't have one in their store yet, April 20th or so, so I have not been able to compare.
