Redsn0w 0.9.6 b5

 

The iPhone-Dev team today released Redsn0w 0.9.6 b5, a carrier unlock and hactivation tool for iPhone 3G and iPhone 3G S with iOS 4.2.1. Redsn0w 0.9.6 b5 is the PwnageTool 4.1.3 alternative for Windows. It can be use to upgrade the modem firmware version in iPhone 3G and iPhone 3 GS from 05.14.02, 05.15.04 or higher to the unlock supported baseband 06.15.00. Here we use iPad OS 3.2.2 with Redsn0w 0.9.6 b5 to update the baseband of the iPhone 3G or iPhone 3GS to 06.15.00.  After the baseband  upgrade, we can use Ultrasn0w 1.2 to unlock the device.

    i had to restore to apple settings via iTunes because hardly anything worked like the calender, choosing a contact when trying to text sum1, not even a simple tally-counter!

    I did the redsn0w thing. I went through all the steps and installed cydia. But on my phone, cydia is just a blank white icon, when i click it, it does nothing. What do i need to do to fix this? i have the 6.15 and the 4.2.1 and all that.
