How can i downgrade from os4 to 3.1.3 on a factory unlcoked iphone 3gs?
I have a factory unlocked iphone 3gs, which worked wery nice on 3.1.3. Since os4 came out, i upgrade it, but i cannot jailbreak it.
Also, i canno put the tonibile setings on the iphone, I can't se that option anymore. So my question is....
Can i downgrade to 3.1.3?, or is there a custim os4 firmware that would allow me to install cycdia, and also config the iphone for tmobil mms and web setting?
If yes, than can someone give me some advice?
I upgraded my factory unlocked 3GS from 3.1.3 to 4.0... cellular data (GPRS) has stopped working after upgrade.. working on wifi is fine though... does this have any relation whatsoever to a jailbreak? any ideas ? should i restore back and wait till a jailbreak arrives?
Get your SHSH for OS 3.1.3 as soon as possible. Then you can downgrade when you want to.
