yes

Yes as long as you call the carrier of that phone and get the unlock code and as of June or July 09 centennial will be At&t they bought out centennial
You need one with a SIM Card slot. From there, find a GSM carrier, buy a SIM card and slip it in. (T-Mobile, AT&T, and every European carrier is GSM).
You can't put a SIM card on a Nextel Phone, since it's a CDMA carrier. The only carriers that use SIM cards are GSM ones, like AT&T, T Mobile, Centennial Wireless, etc.
yes they are a gsm carrier.
Centennial Wireless has merged with AT&T. The merger took place November 7, 2008. Centennial Wireless had operations in rural areas of the Midwest and the Southeast.
Gsm
AT&T brought Centennial Wireless. The sale is expected to close in the second quarter of 2009.
Not yet, Im pretty sure someone out there is trying to figure out how to. Straight Talk runs on the Verizon's network so maybe/possibly the Verizon Blackberry phones might be the best candidate.
It's a gsm/umts network. There's no cdma carrier in the Philippines.
I just got the official letter today from verizion, they will be fully switched over on July 31st. 2011. Cdma will go live in select markets in Louisiana and Mississippi and centennial's gsm signal will die, you will have to have a verizion handset to continue service.
