I just upgraded my mom to a iphone 5S. She's had a 3GS for far too long. Thing is, she accidentally upgraded it to 6.1.3. This makes the phone extremely aggravating to use due to how slow it is. I've never jailbroken the phone before, nor saved any shsh blobs for it. I haven't jailbroken an iphone in ages either. Is it possible to get this 3GS off of ios 6 at all? much appreciated!
