One of our secret agents let us know that T-Mobile and RIM are throwing launch parties for the 8520 Curve aka Gemini starting July 20th. They will be running for 2 weeks and they have 51 events planned. You need an invitation to register for the event but you can check it out at the link below and yell at your T-Mobile Rep to get you in.
So if the device is getting launch parties starting the 20th and it has yet to be announced I guess an announcement is coming soon???
