Perosnally I would stay away from the Glyde, they are known to have a lot of issues with the screen not being responsive and not working around the edges. My friend was going to get one so I did some looking into it and didn't like what I found. If you do a search for phone reviews, you will see what I mean. phonescoop.com, howardforums.com have reviews and can point you in the right direction.
From what I heard, they are in the process of discontinuing the Glyde.
What don't you like about it? My Pearl was my first blackberry so I am amazed at what all it can do. A lot of people don't like the suretype but I have found it to be very useful. I had an env before the pearl and the full qwerty was nice but I can go faster with the suretype.
That is amazing. I am surprised they covered it under warranty. I am stuck with Verizon as they are the only company that gets good signal around here, I am happy with them, probably has something to do with us getting a 22% discount because Stephen works for UPS
