how can unlock i phone, how can unlock i phone

YOU cannot. You can ask the carrier it is locked to if they will, and if they say yes, then they will tell you how to proceed. Only the carrier it is locked to can authorize an unlocking.

Contact the carrier your phone is locked to to see if they offer unlocking & what the procedure/cost is. That is the ONLY official way to do so.

sorry timkilted (sorry if that isn't right)...didn't know it was "illegal" to offer answers offline....

It's a violation of the terms of service to offer or promote unlocking and/or jailbreaking, which you were doing here, in this forum. Heck, it's "services" like yours that end up generating much of the traffic on these forums when people have problems with illegitimately unlocked phones.

I honestly hope the sale of legitimately unlocked phones in the US lands you in the poorhouse. You're about 2 steps above a telemarketer in my opinion.

read....just said sorry I didn't know it was illegal...take a break buddy. I won't respond again, but wanted you to read what I wrote again....I get it....jeez

Hi, now that apple is selling unlocked Iphone 4. Can I Unlock my AT&T Iphone that I have purchased without plan from Radio Chack?

Not at the minute, it changed in the UK when O2 lost exclusivity so it may change in the future for AT&T phones. But I have to stress it has not changed yet, they are still not unlocking and as they are the only carrier running a gsm phone they may not feel the need to change their policy.

Do you even bother to read anything before you post?

No. You can't unlock it. AT&T will NOT unlock your phone for any reason.
