mic : iPhone 3GS or iPhone 4 ???

now that's the question .... since i'm getting my darling an Iphone as a BEEEEeeeeLAted birthday present .... its wise to get to know which model has got more compatibility with her daily use.

 Let's go through the PROS .... we'll leave out the CONS for a moment

iPhone 4

- Better design
- Video Call (Between iPhone 4 to iPhone 4 and with WIFI only)
- HD Video Recording
- 5MP Camera

iPhone 3GS

- Able to Jailbreak
- Free Apps download and installation after Jailbreak (imagine 100,000 FREE apps)
- 3MP Camera ... still looks great
- Able to customize and modify your on screen look to whatever extend there is available
- Able to use iOS4 which is the same OS as the iPhone 4 (Multitasking, Folders bla bla bla)

Which one you prefer?
