920610 - what cell phones are appropriate for me?

hi
i need a cheap cell phone with the following features:

1. may SMS by one hand without having to look to display screen to make sure where the keys are located. for this, it seems that it has to have keyboard. so touch is optional (not really required). i'm not sure QWERTY keyboard is easy to locate and work with. i've not experienced it. if it's as easy as numbers keyboards to locate and work with, it's ok.

2. threaded-view SMS.
3. no limitation in SMS count and volume. should be able to store them in a high-capacity memory like SD.
4. capable of handling SD/MicroSD at least 8 GB.
5. can export SMS'es to PC for backing up. export format be popular (plain text file, Excel worksheet, etc.)
6. same for contact list.

7. controllable via PC. eg. may SMS via PC. maybe connected to PC via WiFi, Bluetooth or USB cable. it's ideal to be able to communicate with people via PC and it via phone, that's i may dial and speak with them by software in PC, by headset and sound card of PC without having to even touch the phone.

8. has flashlight or something like it.
9. listen to music via Bluetooth hands free. if some call received, music temporarily suspends and after call resumes.

10. nice quality of camera (phone/video). at least 2M. also stores better formats of video than 3gp which have low fps.

11. long time battery charge.
12. i need some software for writing down what i need during day life. something like notepad.
13. Persian language and date (Jalali) support.
14. automatic date correction via operator (data).
15. has alarm (most have).
16. cheapers, lighters and smallers in size are prioritized.
17. display sharpness and brightness.
18. clear and loud sound and voice.

what's my best choice(s)?
thx
