Unlock 1.1.2 in Grenada

[oachaudh]

hey guys I'm studying Grenada and I sucessfully unlocked my iphone and upgraded to 1.1.2 and it recognized the new sim. The only problem was that
I couldn't recieve or make phone calls same with sms, i know i the iworld program but Grenada is not listed in the countries. I tired a lot of nearby countries but with no luck.
Anyone have any ideas? I use BMobile down here
thanks a lot

I use B Mobile in Trinidad. But my iPhone is an OTB 1.0.2
I never upgraded. Works great. I have roaming and have so far visited UK, Singapore and Australia with the phone. No probs. Maybe you should downgrade a notch?

thanks for the replies
I actually have 1.1.1 running right now without problem
I guess I should ask, is it worth the trouble, from what i've gathered but don't fully understand, editing the appsupport just to upgrade to 1.1.2? any really improvements?
thanks guys much appreciated
