I know I tried to browse he on my HTC Tilt and it was actually fairly easy to navigate. When I came to the site the phone offered me a mobile version...but on my husbands new HTC Ozone and my Samsung Alias II it tries to load up as it does on the PC/Laptop and it's very difficult to navigate.
So unfortunately I don't know what was so different from the Tilt to any other phone that gave me a mobile option. Maybe try mm.elliquiy.com ? I know when I worked with the blackberries on T-Mobile we had to try mm.youtube.com or mm.myspace.com or mm.facebook.com to access the sites in a mobile version. You could try that.
As for must haves...I don't know...if it's a pearl or has an kind of track ball...DO NOT GET THE APP THAT LETS YOU HAVE THE TRACK BALL CHANGE COLORS...for the love of god, don't do it. I don't know how many times I had to master reset a blackberry because of that App. There is a glitch in it. I do know that www.crackberry.com
has a lot of neato stuff for the blackberry though.
Sorry if this is of no help. V_V I tried.
