Hi I have the Iphone with Jailbreak and Gevey (since source was AT & T) for nearly 3 years ago and I have IOS 4.3.3 with baseband 04.10.01, now virtually all apps give me error because it has to be greater than IOS 5 or 6, I want to update it. I followed a tutorial and IOS 6.1 with RedSn0w. but I get a message in English "no remote blobs found" also do not know if the 6.1 is the most recent and therefore do not know if it's the best option because when I plug it into Itunes tells me there is an update to 7.0.4 I would like sabersi: I can upgrade to IOS?? How do I do? What firmware? And does the bb? Thanks a million!
