Hello there, I currently own an iphone 3gs JB tethered, and after about 3 months of use I'm gettings problems on it. Today in the middle of a phone call the call dropped and it said I had no signal. Trying to do something, I tried to respring it, but it didn't work, after a couple of minutes still stuck on the respring screen (the white weel in the middle stuck) I tried to manually reboot the device. Now I can't seem to to make it work at all. Being JB I need to blackr1n it every time I reboot it, but nothing is happenning. Not only it takes a lot of time to get to recovery screen (the usb cable pic), it also get stuck on saurik pic. After 5 minutes it goes back to the recovery screen. I don't have 3.1.2 backed on cydia, so restoring now is not an option. I also don't have access to a mac computer to use pwownage toll. What should I do to get my Iphone back working (and still JB)?
