When i purchased this phone over 6 months ago, I was leary of all the issues that the reviews and comments mentioned. But nonetheless, I purchased it to see how it was for myself. I had a P910i and it paired with my car's Bluetooth flawlessly, but I was extremely bugged that the P990i could not pair up with my Bluetooth on the BMW. But with a couple updates from Sony Ericsson it was fixed.In the beginning there were a few bugs, like the certain softwares on the phone took longer to load (i.e. camera), and if you had a couple programs running together (i.e. music player, camera, web browser) it would have a tendency to freeze up. But the wonderful parts about this phone are that Sony Ericsson's firmware updating team has been doing a great job in keeping this phone up to date and running at it's best, it's features are second to none. (2mp camera - great pictures, Wifi, QWERTY, Sony's music player[MegaBass], PDA, web brower).So don't worry about the other reviews that claim it has bugs, all the majors issues have been ironed out and the phone is running well (with the latest update from SC) It's a great phone, but I only wished that SC made it slight smaller so it wouldn't be so bulky in the pocket.Firmware:Phone: CXC162037 R9G007Bluetooth: CXC162058 R5A01Organizer: CXC162036 R6D23CDA: CDA162007/1 R6D23
