Cell phone desperation

Well, I have reached a crash point now in my tech reality-- my cell phone has well and truly died. It is an old treo 700p which I much much loved and ( apparently) used to death. It has, of course decided to die while I am traveling and at a conference. But that is beside the point. I need to figure out a replacement and Fast. Prefer something I can call and order tonight and get it delivered to the house ASAP. My current carrier is Sprint, but I am not locked into them. My contract is expired, so I have the option of switching carriers if there is a better deal out there.
Here is what we need:

Phone on a network with a fast data connection.
Decent sized screen display for google map usage, web browsing, etc
text
camera
ability to add an application to ssh
good calendar system and able to synchronize with google calendars through some add on
I type on this a lot, so a good keypad for input ( not a number pad mapping and NOT an onscreen simulated keypad, real keys please)
ability to expand storage via SD or mini SD card

carrier need to have a plan where I can put two or more ( by christmas it may be 6) phones on a single plan to share minutes. The first two phones need unlimited text and unlimited data.

suggestions? recommendations? please respond here as my phone is dead and twitter is unreliable. I am hoping to order something tonight.

Strange, mind numbing cell phone withdraw symptoms already setting in..... waiting for the twitching to start...
