I'm trying to research to purchase my first PDA / smartphone, and have found a large number that appeal to me, but know that I both haven't seen everything and don't have all the facts, and don't even know if I can all the things I want.

Here's a basic layout of what I'm hoping for:

NEEDED
Good Camera (2.0-5.0 mp, higher preferred)
Internet Connection
Chat / Email / Browsing
Plays Videos (youtube, cnn, etc)
Global Access / Unlocked
GPS
Music Player
Weather

WOULD LIKE
QWERT keyboard or touch screen for easier messaging / internet use
WiFi / bluetooth / FM
Ability to use SKYPE or other video/audio internet communications
Flash support to watch tvlinks
OS able to be hacked / modified / customized

My intention is to buy an unlocked phone that I can take with me on travels. I'd just buy prepaid sim cards in whatever country I'm in to make actual phone calls (including in the USA where I am now, I'll likely keep normal phone calls to a minimum, but local incoming would be quite nice)

I'd like to replace my camera, mp3 player, and laptop, though not expecting any of those to be as good on a PDA/phone as not on one, I'm hoping for a good selection.

I plan on setting up a dedicated server over here to host music  (and if i can get good enough streaming and a good data plan, videos as well)  This way I could have a friend up-keeping a server that we'll share stocked with all the music we want, and access it anywhere where I have an internet connection (wifi if possible, or just via satellite)

So, Suggestions?  I have some further questions on the implementation of my plan.

-What all providers cover either global solutions or europe and N america?  
-Who offers good unlimited data plans (and how much is unlimited really?)
-Does anyone offer ONLY data plans, no voice?  Any PDAs more geared in this direction?
-How well does streaming video / music work from: free sites, the providers free services, dedicated servers that aren't necessarily built for streaming out mass info.
-What OSs are available and what are the differences?
-Can any run those "work on your computer from another computer" type of friendly trojan software?


Has anyone used a smartphone / PDA in this way, essentially to host a rather large music selection and be able to access it via the ftp or html, or used one regularly to get music streaming off of free sites?

I haven't figured out exactly how I'm going to host, edit, sort, playlist, etc... but I got my friends on that part hopefully will be able to get it down, I need to figure out what I'm gonna buy!

I'll go up to the 500-600 range, but will obviously appreciate any lesser known devices that could do what I need.  I've checked out an love the Nokia line (n95, n71, etc)  If any of their other models sound particularly up my alley, go ahead an suggest it.

  I also don't know much about the providers and their plans, though I've seen a number of data plans that are pay by the byte or limited to like 100 mgs a month.  Therefore, if there's any particularly good providers for using lots of data where I might not have WiFi or something free, let me know.  

Tell me If I'm going to be limited on what phone to get by what providers will offer good data plans and cheap or nonexistent voice plans.  I plan on going to Cyprus pretty soon, but being back in N America, and traveling all over in the future.



Sorry to ask such a huge and noobish question, but I really don't know much about the whole situation, and would love to be able to nail a solid device that I can keep for years and have it do all the things I need.

Thank for any help, even if you can only answer one part of my post!
