One user had this to say about the 8800.

My review on the 8800:-

Got mine yesterday morning. Gave Adam - GSMPS - a call as soon as I had the unit in hand to get it unlocked. Amazingly, he had the instructions and the code for me within 4 hours!

Put my TMO SIM inside. EDGE picked up right away. Transferred my BIS email service books from the PEARL to the new 8800 - worked like a charm.

The unit itself - Black with a blue tint on it, looks really nice. Its a bit heavier than the 8700G, and a bit wider, but for me that was good. The grip on the phone is a lot more stable.

Keyboard layout is a bit tight, but only takes a few minutes to get used to, and you're well on your way to typing at the same speeds as 8700G, if not faster. The keys have a little edge on them, which makes pressing each key easier.

The buttons, SEND, MENU, BACK, and END are very soft and easy to press, unlike PEARL. The trackball is the same size as PEARL, but the casing around the trackball kind of makes it seem a bit wide. Trackball is a lot more stable, and it feels firm, again, unlike PEARL.

So far, all the keys on the keyboard, and all the buttons on the phone are designed with perfection in mind.

The speaker phone on the 8800 is LOUD and CLEAR. No hiss or distortion. I read somewhere that the 8800's speakerphone is unlike the PEARL's or the 8700's. 8800 speakerphone has 2 vertical speakers built inside, rather than just 1.

The mic also works very well. I tested the mic with speakerphone from about 5 feet away, and the other person on line could hear me fine.

The screen is VERY sharp and crisp. The best screen so far on any of the BB's.

Unlocked on TMO works great. Service, BIS, Emails, GPS w/ BB Maps, BB Messenger, Google Talk, MMS, SMS, pretty much everything works well just the way it used to on my black TMO Pearl. The only thing that I don't like, and I know a fix of that is coming soon, is the Cingular theme. Its very annoying, and I hate it

Overall, I like the phone a lot. Even though its the same processor as the 8700, it seems to run a bit faster, and smoother. Keyboard is nice once you get used to typing on it.

The battery has been running fine since yesterday, and I've been using it full throttle. Its currently at 45%, which is AMAZING.

The only downside on the phone is that its kind of big. If you've used an 8700 and a Pearl in the past, you won't like this about the 8800 either. Its kind of bulky.

Hope this helps?
