I have an iphone 3g running 4.1 and I need an unlock. Please help!?

I accidentally upgraded to os 4.1, but I have t-mobile and I need it to be unlocked. I am pretty experienced with the iDevices, I know how to use redsn0w and quickpwn etc. There has to be a way to either downgrade the baseband or unlock the 4.1 baseband, right? Thanks so much for anyone's help!

Hi. You can unlock your iPhone 3G safer and easier using remote unlocking service. You can get the remote unlocking service for an iPhone 3G from Unlock-Zone.Com This method of unlocking an iPhone is safe, simple, affordable, quick and permanent. It doesn't require a jailbreak too. Good luck.
