AT&T now want to use my tmobile sim possible?

[tonyp2001]

i purchased an iphone 16gb 1.1.3 yesterday and didnt want to wait to hack it for tmobile. i already have a tmobile sim account active, so now that its on at&t activated can i still hack it to use tmobile? if so How or what steps would i have to do. thanks Tony.
