After using it for many months now, I absolutely love this device. Not only does it function beautifully, it is itself beautiful. After downloading a fiery fractal background image from google (hint: you can zoom the image in once before making it your home screen background to avoid the "white line" effect) I find myself picking the Pearl up and playing with it simply because it makes me feel good. Blush.The internet email works very well with my MSN hotmail account, the calendar, address book, tasks and memos sync smoothly with Outlook using the USB cable, and the thing holds a charge forever. If you use the camera, check out its menu, because you have several different resolutions to choose from, as well as flash settings. I added a 2GB microSD card for photos, and it went smoothly. The only drawbacks are that GPRS and EDGE provide relatively slow download speeds compared to CDMA networks, and the Pearl does not have a stereo headphone jack.Finally, I initially did not like the Smart Type keyboard, and was chomping to get a qwerty model, but now that I've used it a bit I realize it has learned from my typing, and somehow produces the right word almost all of the time, and I like the slim form factor so much I'm keeping this device.I have the T-Mobile MyFaves plan and love it. It works. I have no long distance charges to my family and friends, all on different carriers.T-Mo will indeed unlock your SIM card after you've been with them for three months, free of charge, so you can go to Europe, for example, and use a local provider's SIM card for those extended trips. Also, T-Mobile has operating agreements for roaming all around Europe, Canada and Mexico, again with no sign up fee. No nickel-and-diming you like Cingular does.I cannot say enough good things about both T-Mobile and RIM customer support. (I'm a geek and reloaded the operating system for fun. What can I say. Cough.) They are fantastic. Yo, Qwest, AT&T;, are you listening? Take lessons from T-Mobile. Where else does a customer support rep say "What other issues are you having? Let's stay on the phone and get them all resolved." Yes, I'm a happy customer.
