ready for a challenge? tricky one... i need help.
i have jb/unlocked iphone 3GS, running 3.0.
I desperately need to update it with a newer version os so that my apps will run and sms will work. (not to mention my camera just stopped saving pictures when you take them and it's just generally laggy and acting weird.)
here's the problem... cydia crashes each time i launch it.
i have tried tiny umbrella, but i get the 'apple not signing' error message, so it will not save my shsh blobs.
I have been able to back everything up to itunes, so at this point, i don't care if i lose everything and need to start over completely.
what are my options?
If i do a factory restore, it will update to 5.0, correct? and the only jailbreak for 5.0 is tethered.. is there an unlock for 5 yet? (i'm with tmobile, so i must have an unlock) At this point, i'm thinking a tethered jb wouldn't be the worst thing. will a tethered 5.0 jb/unlock even work on my iphone?
any other ideas/suggestions?
