T-mobile Phones??? T-mobile Dash vs. T-mobile Blackberry Pearl.?

I'm changing phone services and have decided on T-mobile, however, I can't decide on the phone. I have narrowed it down to the T-mobile Dash and the Blackberry Pearl(not the 8120 yet to be released). I am use to a full keyboard so these were my best choices. I know that both allow you to check your e-mails but do i have to pay monthly for this, even if I'm at a T-mobile hotspot(This is not the most important thing to me, but I would use it a ton if i didn't have to pay extra) I assume both keyboards can be locked, am I correct? Which is easier to text with? Which is better/ more comfortable to talk on? Which is easier to use(overall, and the QWERTY keyboard)? Which has better performance? What messaging services can i use from each, AIM, Yahoo, MSN, etc.? What about any additional functions? Any other comments, I want to hear them!!!

ok first off, the dash and the pearl are both excellent phones, but i think you might be talking about the blackberry curve, because it has a full keyboard while the pearl had two letters to a button, and the blackberry curve has wi-fi as well as the dash. Now, there is a montly fee of twenty dollars for unlimited web browsing and email, but the blackberry's can not sync with outlook email. Also the dash is a windows mobile phone, so you can upload your microsoft word, excel documents onto it etc. and you can watch movies on it's window's media player (pretty cool). Yes the keyboard can be locked on both types of phones, the texting is a little tricky on both phones, but once you get used to it, it's fine. The blackberry curve's internet is a little slower than the dashes because they have completely seperate internet add-on packages. you can set up any email from the blackberry except outlook, but over all both phones are awesome. The dash doesn't look as cool, and the blackberry has more accessories to go with it. Hope this helps alittle..! good luck
