Just got the new BlackBerry 8800 today (through T-Mobile). So far, I love the phone. I've been looking at a bunch of phones lately, and trying to figure out the perfect fit. It came down to what I use my phone for...and that's email, text messaging and making phone calls.
The 8800 uses the 4.2 version of the OS...by far BlackBerry's best one yet. I love the interface, and I especially love the trackball.
I'm excited to test out the new iPhone when it comes out, but my gut tells me that this is the best solution for the next year.
