Will My SIM card work?

[Spiderxkx]

Ok guys I'm new to this forum and this is my question. I'm planning on going to Mexico in about 3 weeks. I was planning on buying an iPhone 3gs that's Jailbroken and Unlocked to GSM carrier's SIM. Will I be able to just put in my SIM card with the phone company I have in Mexico (Telcel BTW)? Or will I need to do some others things besides to be able to get it to work?

The iphone is OS 4.2.1, baseband 5.13.04, any help on this topic will be greatly appreciated

If the 3GS is already Unlocked then yes... you should just be able to throw ANY sim car in ad go.
