Possible jailbreak all device 4.x with webapp

[relicwqa]

Is it a possibility to jailbreak all device on any 4.x FW. By make a webapp. And putting that webapp in folder. Can u make a code, so when u open a folder to access that webapp. To attacks and override the system that makes native folder on springboard to jailbreak the device?

Like finding a exploit on the native folders on springboard?

Don't think so. Just downgrade to 4.0.1. Then use jailbreakme.com.

I used limera1n to jailbreak my 3GS running on iOS 4.1, and unlocked with ultrasn0w after upgrading to the iPad 6.15.00 baseband. No problems with my megaphone.
