ok bro.

<1> activate iphone with original sim or programmble sim.

<2> open redsn0w and select original firmware.click next after patching kernel u can tick only INSTALL CYDIA and follow the instruction.

<3> now all jailbreak data install and flashing nor part.

<4> after that reboot your device if cydia doesn't open then reboot your device again.at that time your device stuck at apple logo.

<5> not open redsn0w and select original firmware and next. At this time u can tick only JUST BOOT THETHERED only and follow the instruction. u can see pineapple logo and your device reboot automatically.

<6> now check cydia and safari both working fine.
