Can I put a Straight Talk sim card in this 3G iPhone?

Hi -- I'd like to buy this refurbished iPhone from Game Stop (http://www.gamestop.com/iphone/cell-phones/iphoner-3g-16gb-for-att-black-gamestop-premium-refurbished/98123?affid=9797&cid=ppc_60000001) and use a Straight Talk sim card (which I haven't purchased yet) with it. Is this possible? Will I be able to use phone, texting, Internet, etc? Any advice?

Yes, Straight talk sim cards will work with any phone from AT&T, T-Mobile or any unlocked GSM phone

the only drawback is you will be limited to Edge (2g) speeds due to T-Mobile networks working on different 3g frequencies than the iPhone (and AT&T) use.
