I just bought an iPhone 3GS from Maxis recently, i found out that the screen tends to be yellow compared to my iPhone 3G. Besides that, i found out that the color representation in my 3GS is also less vivid.Is this normal or should i get it replaced? Thanks!

I'm also facing the same problem. Does your screen have a yellowish tint? My color appears to be very washed out. Thinking of claiming warranty.

iPhone Generation: 3GS(16GB)
Factory Unlocked: Yes(Maxis Set)
Current Firmware:3.1.2
Network: Maxis Mobile
Itunes Version: 9.0.1
OS: MacOSX 10.6.2
Jailbreaking Software: Blacksn0w RC3
Problem encountered: Self Reboot(Once), No Gps, "can't activate cellular data network"
Step Taken: Dfu mode restore to original firmware

Remarks: Last, Sunday while i was browsing my sms my Iphone reboots by itself so i decided to restore it. After restoring, the phone keeps saying "can't activate cellular data network"( i had to turn on/off airplane mode to solve this problem). Until yesterday, i can't tolerate any more and restored my phone again.Now it drops signal(twice a day).Please Help!!! BTW, i found out that my iPhone screen is very yellowish. Is it normal?Thanks in advance.
