can i flash blackberry curve 8900/ pearl 3G into metropcs network

metro pcs is the cheapest plan on the market although its coverage sucks.but yet as long as it coves my area.
i would like to start using metropcs and i want to buy a new blackberry to go w/ it.
i only like the new pearl 3g and curve 8900. i kw tht metro pcs supports curve 8830 but i am not sure abt the others blackberrys.
i will buy a unlock phone from manufactured instead of the ones from the phone companies.
can metro pcs support pearl 3G and curve 8900 ? or other balckberry phones ?
thx alot (:

You can have Metro pcs on Blackberry 8330 for sure. But am not sure about curve 8900 because it is a GSM network based device and Metro pcs is a CDMA. So they wont be compatible. I dont think you cab get Metro pcs on Sim card :no: For more info, see this: http://forums.techarena.in/portable-devices/1229872.htm
