Me again I know I should edit previous post but let me show you the progress

What happened was; I didn't get any answer again from TMO so decided to play with setting on BB. I set in TCP the APN for wap.voicestream.com and left username and pass blank. Then I went to browser settings and changed everything to T-Zones.
After that, nothing was going on, at least I didn't notice, I went to Certificates and went throw all of them changing some of them which were "Not allowed" to "Allow". I changed everything what had tmobile in address to allow. Guess what? BBToday Weather started working but my polish IM still cannot connect...I'll keep trying and let you know as soon as something happens again...
