This phone is both very good and very bad. It's good because it's capable of pretty much everything a phone can do now-a-days. However, it's bad because it is very deceiving as to what you get. On the box and on T-Mobile's website, you are informed you can use instant messengers including AOL IM, MSN, Yahoo, ICQ, Google Talk and Jabber. What they don't tell you is in order to use them, you must have a BlackBerry plan. Every other phone, you don't! Why? No reason. Another thing, you have to pay for the client to sign in and send messages! Sure, there's freeware out there for you to find, but it's not as convenient. Another complaint is the BlackBerry packages themselves; none of them offer free nights and weekends nor unlimited Mobile to Mobile. In order to get everything, you need a Get More plan with Unlimited Mobile to Mobile, BlackBerry and Unlimited Text Messaging services. That adds up fast.As far as the device itself goes, there are pros and cons. One thing to note is it takes a very long time to get used to navigating with this phone. There are no left/right action keys so everything is done with menus. Yes, this is nice because it allows more options but it takes longer to do repeated tasks. Another thing that can be good/bad depending on how you view it is that every application maintains its state when you close it. That is, if you go in your phone book, scroll to the "R"s, call your buddy, say, Randy... hang up, open your phone book, it's still at his entry. I'd prefer if it started me at "A" again like every other phone.SureType is not a very easy way to type. Granted it has a great dictionary and the ability to add and delete words from it when you want, it still lacks in key areas. Even if you teach it a word, it still may default to some garbled letters that just couldn't be a word. It does not predict text -- that is, it does not let you type three letters and give you a recommendation. Example: you type "telev"... it should let you just press a key to predict "television". Nooo, you have to type out every letter. So what if I only have to press each key once!? I still have to type each letter! Every other phone on the market lets you just pick a word half-way through spelling it. It's also hard to get used to a QWERTY keyboard with shared keys.All in all, a great device. I'm sure other reviews point out the positive. I just find it hard to use because of the small details. It's also deceptive from a price standpoint. This review could go on about other aspects of the phone, but I'm sure you can find other tidbits of information elsewhere.
