T-Mobile USA's version of the Pearl Flip 8220 will only cost slightly less than the Curve when it goes on sale, a T-Mobile rep claims in a forum post at TmoNews. The BlackBerry clamshell will purportedly sell for $150 for new users agreeing to a two-year contract and should climb to $200 for one-year plans. Existing subscribers who qualify for a full upgrade will pay $18 more to trade up, while a full retail price will cost $350.

The T-Mobile edition adheres closely to the reference design from Research in Motion but is planned to come in red trim and support the carrier's HotSpot@Home Wi-Fi calling service, which bridges between GSM and Wi-Fi to save on calling time and improve reception inside.
