at&t to T-Mobile on Bold and BES

[shadysprings]

I got fed up with at&t due to poor reception and switched to T-Mobile for the UMA. I live in the hills so I don't expect great reception. What I really didn't expect was to now having full 5 bars of reception and not even needing UMA!
Love T-Mobile so far!

So here's my question please:
I unlocked my Bold and am now using a T-mobile sim card. I signed up for T-Mobile Blackberry BES. However, I'm still using ATT.blackberry.com. I think

Do I need to delete the BES stuff from at&t and install T-mobile. I haven't changed anything and it still works.

you should change your wap settings btw, but no you do not need to reenter the bes info.

i would actually recommend using wap.voicestream.com because others have recommended it or you can use epc.tmobile.com
