Hi peoples! I have some questions! 1.Is ios4.1 jailbreak faster than ios4? Taking into account I will install the same things, sbsettings, synchronicity, ifile, infinifolders, infinidock and istrings. 2.Are those apps compatible fully? 3.I would like to keep my app saves, if I restore from a backup will it affect anything? 4.Is it possible to press the update button and replace the itunes firmware with custom?
