T-mobiles data throttling & ATT merger ?

[masetas]

Just saw that T-Mobile is offering 2 lines with unlimited everything (well data is unlimited but throttled after 2gb) for $50 and still wondering if the throttling can be removed i want to have a phone that i can be on a call and surf the web at the same time and was planning on getting me and the wife the new SGS2 when it comes out for Tmobile and finally getting her to let go of her old phone and upgrading to Android.

But if the ATT/Tmobile merger does happen how will that affect my account will i have to accept whatever plan change att offers me or would i be able to keep the one i signed up for with Tmobile.

Its a new 2yr agreement that i would have to sign so so that really sucks
