I've had a HTC Desire for just over a year and I love it. It does everything I need it to and has such a wide array of apps that whenever I'm bored there's always something to do to pass the time, and the music system works wonderfully with great sound quality. Texting/emaling from it is very easy and the keypad is laid out really well, so it's definitely a phone I'd recommend. The only problem is that it has a habit of breaking a lot, so don't get it if you're clumsy like me!
I have a Samsung Captivate, which is AT&T's equivalent to the Samsung Galaxy S (the first one, sadly). I like it, though I'm pretty terrible with keeping it charged. I'll be keeping this phone for another year until I get a new one if I don't lose it first like the other cellphones I've had.
I have a Nokia 3310 classic, a pretty basic phone for a guy who just needs to use it to call, SMS and play some no frills games to past time. For playing mainstream games and surfing the net, I can always use my computer.
I have a Virizon LG Dare. It's quite an old phone and Ive ahd it for years. Unfortunately, it may be breaking, it has a problem where it occasionally thinks it's battery is fake. I believe this may be a sign that either the phone or battery is on it's way out. It's getting replaced with an iPhone which Im supposedly getting as a Christmas gift.
