does anyone here have problem with their 3gs screen looking abit washed out? i compared one unit with another one of my friend's unit, the colours on his screen looks much nicer, looks like it has a higher contrast. is there anyway to fix it?

yes, both the brightness on same level, auto brightness was turned on.

guys, if i jailbreak a brand new iphone 4, and let's say in the event where i need to send the iphone back for warranty, after resotring it back, can apple still detect that it's jailbroken and tell me warranty void?

thanks
