Hi y'all.
Re the prepaid SIM cards, you are best to go onto ebay
www.ebay.com and buy these.. you can get them for around .USD99 cents plus postage. The triband phones are now way out of date and some places in USA they cant be used. The quad band phones are the way to go these days.. eg: the RAZR phones. I had this problem when I first came to live in USA so I know what I am talking about. Some places Cingular GSM is better other places Tmobile GSM is better. Hope this helps you all out..
