Odd, I upgraded from 314 to 348 and UMA is now rock solid, you might have done something wrong on the e-screens
Odd as well, I have read of people that made UMA work on their unbranded berries, you need to put the t-mobile certificates and then activate them through the e-screens. Other option is to re-brand your berry
Take a look at forum called "UMA unlocking" at crackberry, uma-unlocking-201539 (sorry, can't post links just yet)
