Welcome to the Blackberry side of PPCGeeks.
Your like most of us, we're all coming from WinMo. You can load a OS/ROM onto the Blackberry Storm ie. Leaked OS or Hybrids.
We have a Blackberry Messenger Group based out of PPCGeeks.com its a stickied thread...Or you can PM me your Blackberry PIN and I'll send you an invite if interested.
These are sites that mainly focus on hot rodding and tweaking berrys.
Blackberryos.com and bbhyrids.net
Beside all that if you need any just ask, we'll go the best we can.
But please dont forget where you come and when you come across any valuable info bring it back home...!O!
