Go into options, then advanced options, then service books.
delete the 2 wifi tcp/ip entries.

Reboot the curve.

The 2 wifi tcp/ip entries in service book will reappear after the reboot.

Next go to mobile.blackberry.com with the bb browser and click on help.
click the hotspot@home(uma) is not working link and follow the instructions to install the root certificate and the trust certificate.

Reboot again and see if you should have UMA

OR just bump up to 4.5.0.42

I upgraded from a Very Stable.18 to this, and it bricked my berry. Had to do some JL_Commander brain surgery to get back to Stock T-Mo OS... the benefits of the OS upgrade were not that great for me... and I will probably have a bold by the time the " OFFICIALLY " release this OS... or maybe not!

I did some research on the 8800's and it should work fine, minus a couple of feature errors (primarily HTML viewers and video errors), similar to the 8300's but I found the 4.5.42, more stable than the 4.5.37 and I believe they fixed the "memory leaks" (although I have never experienced anything detrimental), but its not being shipped out on any phones yet, they're still shipping the .37 on Rogers and Vodaphone is shipping on .18 even (which has nothing to do with US users anyways).

But word to the wise, Tmo users beware, make backups of all your stuff for fear of it tripping up your phone, it didn't with me yet, but i'll report back if it do...
