Mobile Help Needed

"It's difficult to get used to a new phone after a certain age", "You can't afford not having a smartphone, you work in hi-tech for God's sake, it ruins your image", "Stop using gadgets from the 70s, they make you look old" are just a few comments shot at me since I told people I need a new mobile phone.

I am a proud owner of a Nokia 6310. For 9 years. In mobile technology years, that means an eon. It has a monochrome display, but synchronizes with Outlook, where I keep my contacts and calendar. I would have used it for longer, but its sync application doesn't run on Windows 7, the operating system of my new PC at work. Plus, I'm getting a new leased car and I don't think it's worthwhile installing the old hands-free in it. On the other hand, the phone doesn't have Bluetooth to communicate with a headset. Since I can't synchronize the phone or use it in the car, and it's 9 years old, I decided it's time to replace it.

But with what? The possibilities seem endless. Some swear by Apple's iPhone, some by Android-based smartphones. But do I need a smartphone at all? I made a list of useful features, but haven't found any unbiased site or person to tell me what phone I need based on that list. Here goes: large screen and buttons (no qwerty keyboard), thin, updated design, sync by cable (for contacts and calendar), Bluetooth with headset and hands-free, decent camera, WiFi, GPS with local maps.

To complicate things even further, in September-October, my employer will sign a new agreement with one of the mobile operators that will possibly include some good models and plans for employees. And the iPhone 5 will be released, should I decide to go in that direction, and the iPhone 4 will get cheaper. So maybe I should buy a cheap model now and go for a more serious one in a couple of months?

I'm drowning in options. Help!
