WHAT PHONE CAN YOU SUGGEST...

at first i was looking for a pda phone specifically the 02 xda2 for the following reasons: os is microsoft office with apps like word and excel and i heard that it's being sold in manila between 5k-7k for 2nd hand and because i need it for my work. after much thought and consideration what i actually need are the following features:

1. a good organizer. not just a calendar and reminder. i need a to do list for a specific day at a specific time, preferably one with unlimited entries.
2. memo pad or notepad. i hate saving notes in my draft messages folder.
3. calculator
4. calendar
5. vibrating alert (i don't care too much for ringtones, beeping alert is fine)
6. high memory capacity
7. contacts must have entries for address, landline numbers and company etc..
8. expandable memory
9. touch screen (preferable)
10. camera, ok but not required.

my budget is around 5k-7k. i'll be using this as a business phone and organizer. i would be willing to go for the t22 my phone if these features are in it.
hopefully pwede i credit card.

i would appreciate any suggestions that anyone can give. thanks (old)
