This is the best phone you will ever buy. I guarantee it, seen with celebrities all over the world, the T-Mobile Sidekick is really like your own personal sidekick. You can literally do everything on it. My personal advice is go for the Sidekick II, instead of the Sidekick I. Although the price is going to be a bit higher, the Sidekick II, is better from cosmetic wise to the actual device.
vs. 
You can tell just by looking at them, which one is the more attractive and stylish choice. If you dont care about that, I still dont reccomend the Sidekick I. When the sidekick I, first came out, it had a lot of bugs and it still does, however these bugs were corrected in the new sidekick. The sidekick one cosntantly drops calls and never has service. For the few extra bucks, go for the Sidekick II. As an owner of each at times, I know what Im talking about.
