Hi everyone. My case may seem a bit too long, sorry about that. So I got this Iphone 3gs 32gb in Shanghai, China. As some of you may know, Iphones which are sold in China officially have Wifi disabled, so the grey market is full of Iphones which are taken apart, modified (Wifi added, 16gb upgraded to 32gb), jailbreaked and unlocked. Thats the kind I got. It had Cydia out-of-the-box, 3.1.3 firmware. So I used it for a while without problems, never cared to save shsh (didnt even know about it that time), until one unhappy day I upgraded to stock 4.0.1. Since then all I get connecting to Itunes is this message: "There is a problem with your Iphone. We're sorry, the iphone you connected maybe be damaged and cannot be activated for service I tried several AT&T sim card and universal activation card (got that from dealextreme) with no result. Custom 4.0.1 ipsw made with pwnage tool bundle didnt work because the phone is not jailbreaked now (correct me if Im wrong) Here are the specs: Model: MB715LL/A Name: iPhone Baseband: 05.13.04 - 6.4_M3S2 Serial: 83936 . BTW when I tried to check SN on apple website, I got this: We're sorry, but this is a serial number for a product that has been replaced So the question is any ideas to get it back to life?? If not, is there any kind of software coming which could solve the case? Like, hactivated 4.0.1 which wont need a jailbreak or something?
